The polynomial that meets the given conditions is:
f(x) = (x - (4 + 6i))(x - (4 - 6i))(5(x² - 2x + 52))
Simplifying this expression, we have:
f(x) = (x - 4 - 6i)(x - 4 + 6i)(5x² - 10x + 260)
Using the difference of squares formula, we can simplify the complex conjugate terms:
(x - 4 - 6i)(x - 4 + 6i) = (x - 4)² - (6i)² = (x - 4)² - 36i² = (x - 4)² + 36
Substituting this simplified form back into the polynomial:
f(x) = ((x - 4)² + 36)(5x² - 10x + 260)
Expanding further:
f(x) = 5x⁴ - 10x³ + 260x² + 36x² - 72x + 9360
Combining like terms:
f(x) = 5x⁴ - 10x³ + 296x² - 72x + 9360
Therefore, one possible polynomial that satisfies the given conditions is f(x) = 5x⁴ - 10x³ + 296x² - 72x + 9360. Note that other valid polynomials may exist as well.

Assume that population proportion is to be estimated from the sample described. Use the sample results to approximate the margin of error and 95% confidence interval n=560, +0. 45 The margin of error is (Round to four decimal places as needed. ) Find the 96% confidence interval (Round to three decimal places as needed. )
The margin of error is approximately 0.0329, and the 96% confidence interval is (0.417, 0.483).
To approximate the margin of error for estimating the population proportion, we can use the formula:
Margin of Error = Z * sqrt((p * (1 - p)) / n),
where Z is the z-value corresponding to the desired confidence level, p is the sample proportion, and n is the sample size.
Given that n = 560 and the sample proportion is p = 0.45, let's calculate the margin of error:
Margin of Error = Z * sqrt((0.45 * (1 - 0.45)) / 560).
To find the z-value for a 95% confidence level, we can use a standard normal distribution table or a calculator. The z-value corresponding to a 95% confidence level is approximately 1.96.
Margin of Error = 1.96 * sqrt((0.45 * (1 - 0.45)) / 560) ≈ 0.0329.
Therefore, the margin of error is approximately 0.0329.
To find the 96% confidence interval, we can use the formula:
Confidence Interval = p ± Margin of Error.
Confidence Interval = 0.45 ± 0.0329.
Thus, the 96% confidence interval is approximately (0.417, 0.483).

Falco Inc. financed the purchase of a machine with a loan at 3.86% compounded semi- annually. This loan will be settled by making payments of $9,500 at the end of every six months for 6 years. a. What was the principal balance of the loan? b. What was the total amount of interest charged?
a. The principal balance of the loan was the initial amount borrowed, which can be calculated by finding the present value of the payment stream using the loan interest rate and the number of periods.
b. The total amount of interest charged can be calculated by subtracting the principal balance from the total amount repaid over the 6-year period.
a. To find the principal balance of the loan, we need to calculate the present value of the payment stream. The loan has semi-annual compounding, so we can use the formula for present value of an annuity to find the initial amount borrowed. Given that the payments are $9,500 made at the end of every six months for 6 years, and the loan is compounded semi-annually at a rate of 3.86%, we can plug these values into the formula to calculate the principal balance.
b. The total amount of interest charged can be obtained by subtracting the principal balance from the total amount repaid over the 6-year period. Since the loan is repaid with payments of $9,500 every six months for 6 years, we can multiply the payment amount by the total number of payments made over the 6-year period to get the total amount repaid. By subtracting the principal balance from this total amount repaid, we can determine the total interest charged.
By performing the calculations for both parts (a) and (b), we can find the principal balance of the loan and the total amount of interest charged.

Find all values of z for the following equations in terms of exponential functions and also locate these values in the complex plane
z=∜i or z^4=i
The solutions for both equations are located on the complex plane at angles of π/8, 9π/8, 17π/8, etc., counterclockwise from the positive real axis, with a distance of 1 unit from the origin.
To find all values of z for the equation z = ∜i or z^4 = i, we can express i and ∜i in exponential form and solve for z.
1. For z = ∜i:
Expressing i in exponential form: i = e^(iπ/2)
Now, let's find the fourth root (∜) of i:
∜i = (e^(iπ/2))^(1/4)
= e^(iπ/8)
The solutions for z = ∜i are given by z = e^(iπ/8), where k is an integer.
2. For z^4 = i:
Expressing i in exponential form: i = e^(iπ/2)
Now, let's solve for z:
z^4 = e^(iπ/2)
Taking the fourth root of both sides:
z = (e^(iπ/2))^(1/4)
= e^(iπ/8)
The solutions for z^4 = i are given by z = e^(iπ/8), where k is an integer.
To locate these values in the complex plane, we represent them using the polar form, where z = r * e^(iθ). In this case, the modulus r is equal to 1 for all solutions.
For z = e^(iπ/8), the angle θ is π/8. We can plot these solutions in the complex plane as follows:
- For z = e^(iπ/8):
- One solution: z = e^(iπ/8)
- Angle: π/8
- Position in the complex plane: Located at an angle of π/8 counterclockwise from the positive real axis, with a distance of 1 unit from the origin.
Since the solutions are periodic with a period of 2π, we can also find additional solutions by adding integer multiples of 2π to the angle.
Therefore, the solutions for both equations are located on the complex plane at angles of π/8, 9π/8, 17π/8, etc., counterclockwise from the positive real axis, with a distance of 1 unit from the origin.

Suppose that you would like to make five hundred thousand dollars. To do so you plan on investing k dollars per month for 20 years. Assuming that your annual rate of return is six percent compounded continuously, how much must you invest each month?
To achieve a future amount of $500,000 in 20 years at a monthly rate of return of 0.5% (6% annually compounded continuously), we need to invest $1,465.68 per month (rounded to the nearest cent).
Given:
Initial amount to be invested = k
Monthly rate of return = 6%/12
= 0.5%/month
Number of months in 20 years = 20 × 12
= 240
Future amount required = $500,000
First, we will find the formula to calculate future amount as we are given present value, rate of return and time period.
A=P(1 + r/n)nt
where A = future amount
P = present value (initial investment)
r = annual interest rate (as a decimal)
n = number of times the interest is compounded per year
t = number of years
Therefore, here A = future amount, P = 0, r = 6% = 0.06, n = 12, and t = 20 years.
Thus, A= 0(1 + 0.06/12)^(12×20)
= 0(1.005)^240
= 0 × 2.653
= 0
The future amount is 0 dollars, which means that we cannot achieve our goal of five hundred thousand dollars if we don't invest anything at the beginning of each month.
Now, let's find out how much we need to invest monthly to achieve our target future amount.
500,000 = k[(1 + 0.005)^240 - 1] / (0.005)
k = 500,000 × 0.005 / [(1 + 0.005)^240 - 1]k

Find the dimensions of the cardboard for which the volume of the boxes produced by both methods will be the same.
c. Which method can you use to solve the system?
The dimensions of the cardboard for which the volume of the boxes produced by both methods will be the same are width = 26 in and length = 27 in.
(c)The method to solve the system is to equate the volume of the boxes obtained by the two methods since they are both the same.
We are given that a manufacturer is making cardboard boxes by cutting out four equal squares from the corners of the rectangular piece of cardboard and then folding the remaining part into a box. The length of the cardboard piece is 1 in. longer than its width. The manufacturer can cut out either 3 × 3 in. squares, or 4 × 4 in. squares.
We have to find the dimensions of the cardboard for which the volume of the boxes produced by both methods will be the same. Let the width of the cardboard be x in. Then the length of the cardboard is (x + 1) in. The box obtained by cutting out 4 squares of side 3 in. from the cardboard will have:
length (x - 2) in, width (x - 2 - 3 - 3) in = (x - 8) in, and height 3 in.
Volume of the box obtained by cutting out 4 squares of side 3 in. from the cardboard is given by:
V1 = length × width × height= (x - 2) × (x - 8) × 3 in³= 3(x - 2)(x - 8) in³
The box obtained by cutting out 4 squares of side 4 in. from the cardboard will have:
length (x - 2) in, width (x - 2 - 4 - 4) in = (x - 12) in, and height 4 in.
Volume of the box obtained by cutting out 4 squares of side 4 in. from the cardboard is given by:
V2 = length × width × height = (x - 2) × (x - 12) × 4 in³= 4(x - 2)(x - 12) in³
As we know
V1 = V2.
Therefore, 3(x - 2)(x - 8) = 4(x - 2)(x - 12)3(x - 2)(x - 8) - 4(x - 2)(x - 12) = 0(x - 2)(3x - 24 - 4x + 48) = 0(x - 2)(- x + 26) = 0
Therefore, x = 2 or x = 26. x cannot be 2 as the length of the cardboard should be (x + 1) in. which cannot be 3 in.
Therefore, x = 26 in is the width of the cardboard. The length of the cardboard = (x + 1) in.= (26 + 1) in.= 27 in.

If tax on food is 4%, how much tax is paid on a grocery bill of
$147.56?
The tax paid on a grocery bill of $147.56, with a tax rate of 4%, amounts to $5.90.
To calculate this, we multiply the total amount of the bill ($147.56) by the tax rate (4% expressed as 0.04). This gives us the tax amount: $147.56 * 0.04 = $5.90.
Tax amount = Bill amount * Tax rate
In this case, the bill amount is $147.56 and the tax rate is 4% (or 0.04).
Tax amount = $147.56 * 0.04 = $5.90

A line segment PQ is increased along its length by 200% by producing it to R on the side of Q If P and Q have the co-ordinates (3, 4) and (1, 3) respectively then find the co-ordinates of R.
To find the coordinates of point R, we can use the concept of proportionality in the line segment PQ.
The proportionality states that if a line segment is increased or decreased by a certain percentage, the coordinates of the new point can be found by extending or reducing the coordinates of the original points by the same percentage.
Given that line segment PQ is increased by 200%, we can calculate the change in the x-coordinate and the y-coordinate separately.
Change in x-coordinate:
[tex]\displaystyle \Delta x=200\%\cdot ( 1-3)=-4[/tex]
Change in y-coordinate:
[tex]\displaystyle \Delta y=200\%\cdot ( 3-4)=-2[/tex]
Now, we can add the changes to the coordinates of point Q to find the coordinates of point R:

Box R's coordinates, after a 200% increase from PQ in its lengths, are (-3, 1) as determined by multiplying PQ's x and y displacement by three and adding those to the original coordinates of P.
Explanation:To solve this problem, we can use the concept of vectors and displacement. We know the line segment PQ x-displacement (x2 - x1) = 1 - 3 = -2 and its y-displacement (y2 - y1) = 3 - 4 = -1. Noting that the point R is generated by increasing the length of PQ by 200%, the displacement from P to R would be three times the displacement from P to Q. Therefore, Rx = 3*(-2) = -6 and Ry = 3*(-1) = -3. Since these displacements are measured from initial point P(3,4), the coordinates of R would be (3 + Rx, 4 + Ry) = (3 - 6, 4 - 3) = (-3, 1).

6. Find the Fourier transform of the function f(t) = sin x sin x/2 dx. x² And hence evaluate To 1+t, if −1≤ t ≤0, - 1-t, if 0≤t≤1, 0 otherwise. [5]
The Fourier transform of the function f(t) = (1/2π) ∫[from -∞ to ∞] F(w) * e^(iwt) dw.
To find the Fourier transform of the given function, we will apply the properties of the Fourier transform and use the definition of the Fourier transform pair.
The Fourier transform pair for the function f(t) is defined as follows:
F(w) = ∫[from -∞ to ∞] f(t) * e^(-iwt) dt,
f(t) = (1/2π) ∫[from -∞ to ∞] F(w) * e^(iwt) dw.
Let's calculate the Fourier transform of f(t) step by step:
f(t) = sin(x) * sin(x/2) * x^2.
First, we'll evaluate the Fourier transform of sin(x) using the Fourier transform pair:
F1(w) = ∫[from -∞ to ∞] sin(x) * e^(-iwx) dx.
Using the identity:
sin(x) = (1/2i) * (e^(ix) - e^(-ix)),
we can rewrite F1(w) as:
F1(w) = (1/2i) * [(∫[from -∞ to ∞] e^(ix) * e^(-iwx) dx) - (∫[from -∞ to ∞] e^(-ix) * e^(-iwx) dx)].
By applying the Fourier transform pair for e^(iwt), we get:
F1(w) = (1/2i) * [(2π) * δ(w - 1) - (2π) * δ(w + 1)],
F1(w) = π * [δ(w - 1) - δ(w + 1)].
Next, we'll evaluate the Fourier transform of sin(x/2) using the same approach:
F2(w) = ∫[from -∞ to ∞] sin(x/2) * e^(-iwx) dx,
F2(w) = (1/2i) * [(2π) * δ(w - 1/2) - (2π) * δ(w + 1/2)],
F2(w) = π * [δ(w - 1/2) - δ(w + 1/2)].
Finally, we'll find the Fourier transform of x^2:
F3(w) = ∫[from -∞ to ∞] x^2 * e^(-iwx) dx.
This can be solved by differentiating the Fourier transform of 2x:
F3(w) = -d^2/dw^2 F2(w) = -π * [δ''(w - 1/2) - δ''(w + 1/2)].
Now, using the convolution property of the Fourier transform, we can find the Fourier transform of f(t):
F(w) = F1(w) * F2(w) * F3(w),
F(w) = π * [δ(w - 1) - δ(w + 1)] * [δ(w - 1/2) - δ(w + 1/2)] * [-π * (δ''(w - 1/2) - δ''(w + 1/2))],
F(w) = π^2 * [(δ(w - 1) - δ(w + 1)) * (δ(w - 1/2) - δ(w + 1/2))]''.
Now, to evaluate the given expression To 1+t, if −1≤ t ≤0, - 1-t, if 0≤t≤1, 0 otherwise, we can use the inverse Fourier transform. However, since the expression is piecewise-defined, we need to split it into two parts:
For -1 ≤ t ≤ 0:
F^(-1)[F(w) * e^(iwt)] = F^(-1)[π^2 * [(δ(w - 1) - δ(w + 1)) * (δ(w - 1/2) - δ(w + 1/2))]'' * e^(iwt)].
For 0 ≤ t ≤ 1:
F^(-1)[F(w) * e^(iwt)] = F^(-1)[π^2 * [(δ(w - 1) - δ(w + 1)) * (δ(w - 1/2) - δ(w + 1/2))]'' * e^(iwt)].
However, further simplification and calculations are required to obtain the exact expressions for the inverse Fourier transform.

To calculate the mass of the load, we can use the equation W = m × g, where W is the weight, m is the mass, and g is the acceleration due to gravity. When we simplify this, we see that the burden weighs about 500 kg.
Given that the weight of the fully loaded lorry is 14700 N and the mass of the lorry is 500 kg, we can use these values to find the value of g.
Using the equation W = m × g, we can rearrange it to solve for g:
g = W / m
Substituting the given values, we have:
g = 14700 N / 500 kg
Calculating this, we find that g ≈ 29.4 m/s².
Now, to calculate the mass of the load, we can rearrange the equation W = m × g to solve for m:
m = W / g
Substituting the known values, we have:
m = 14700 N / 29.4 m/s²
Simplifying this, we find that the mass of the load is approximately 500 kg.

For this function, identify 1) the y intercept 2) the x intercept(s) = 3) the Vertical asymptote(s) at x =
The required values would be :
1) y-intercept = (0, 8/5)
2) x-intercepts = (-4, 0), (4/3, 0)
3)Vertical asymptotes = `x = 2`, `x = -5/2`.
Given function: `f(x) = ((x+4)(3x-4)) / ((x-2)(2x+5))`
Let us find the y-intercept:
For the y-intercept, substitute `0` for `x`.`f(x) = ((x+4)(3x-4)) / ((x-2)(2x+5))``f(0) = ((0+4)(3(0)-4)) / ((0-2)(2(0)+5))``f(0) = -16 / -10``f(0) = 8 / 5`
Therefore, the y-intercept is `(0, 8/5)`.
Let us find the x-intercepts:
For the x-intercepts, substitute `0` for `y`.`f(x) = ((x+4)(3x-4)) / ((x-2)(2x+5))``0 = ((x+4)(3x-4)) / ((x-2)(2x+5))`
This can be simplified as:`(x+4)(3x-4) = 0`
This equation will be true if `(x+4) = 0` or `(3x-4) = 0`.
Therefore, the x-intercepts are `-4` and `4/3`.Therefore, the x-intercepts are (-4, 0) and `(4/3, 0)`.
Let us find the vertical asymptotes:
To find the vertical asymptotes, we need to find the values of `x` that make the denominator of the function equal to zero.`f(x) = ((x+4)(3x-4)) / ((x-2)(2x+5))``(x-2)(2x+5) = 0`
This will be true if `x = 2` and `x = -5/2`.
Therefore, the vertical asymptotes are `x = 2` and `x = -5/2`.
Hence, the required values are:
1) y-intercept = (0, 8/5)
2) x-intercepts = (-4, 0), (4/3, 0)

Una persona vuela un papalote en forma de mariposa se ha estimado que el largo de la cuerda es de 50 m y forma un ángulo de 60 con el suelo a que altura vuela el papalote
El papalote vuela a una altura aproximada de 43.3 metros.
Para determinar la altura a la que vuela el papalote en forma de mariposa, podemos utilizar la trigonometría básica. Dado que se nos proporciona el largo de la cuerda (50 m) y el ángulo que forma con el suelo (60 grados), podemos utilizar la función trigonométrica del seno.
El seno de un ángulo se define como la relación entre el cateto opuesto y la hipotenusa de un triángulo rectángulo. En este caso, la altura a la que vuela el papalote es el cateto opuesto y la longitud de la cuerda es la hipotenusa.
Aplicando la fórmula del seno:
sen(60 grados) = altura / 50 m
Despejando la altura:
altura = sen(60 grados) * 50 m
El seno de 60 grados es √3/2, por lo que podemos sustituirlo en la ecuación:
altura = (√3/2) * 50 m
Realizando la operación:
altura ≈ (1.732/2) * 50 m
altura ≈ 0.866 * 50 m
altura ≈ 43.3 m

Identify the period and describe two asymptotes for each function.
y=tan 0.5θ
The period of the function y = tan(0.5θ) is π.
It has a horizontal asymptote at y = 0 and vertical asymptotes at θ = (2n + 1)π/2, where n is an integer.
These asymptotes represent values where the function is undefined and the function approaches positive or negative infinity as θ approaches these values.
Period: The period of the function y = tan(0.5θ) is π.
Asymptotes: There are two types of asymptotes for the function y = tan(0.5θ):
1. Horizontal Asymptote: The horizontal asymptote for the function y = tan(0.5θ) is y = 0. This means that as θ approaches positive or negative infinity, the value of y approaches 0.
In other words, the function gets closer and closer to the x-axis but never touches it.
2. Vertical Asymptotes: The vertical asymptotes for the function y = tan(0.5θ) occur at θ = (2n + 1)π/2, where n is an integer.
These vertical asymptotes represent values of θ where the function is undefined. When θ approaches these values, the function approaches positive or negative infinity.
In other words, the function gets closer and closer to vertical lines but never crosses them.
For example,
if we take θ = π/2, which is one of the vertical asymptotes, the function y = tan(0.5θ) becomes y = tan(0.5(π/2)) = tan(π/4) = 1.
As θ approaches π/2 from the left or right, y approaches positive infinity.
Similarly, if we take θ = 3π/2, another vertical asymptote, the function y = tan(0.5θ) becomes y = tan(0.5(3π/2)) = tan(3π/4) = -1.
As θ approaches 3π/2 from the left or right, y approaches negative infinity.
In summary, the period of the function y = tan(0.5θ) is π.
It has a horizontal asymptote at y = 0 and vertical asymptotes at θ = (2n + 1)π/2, where n is an integer.
These asymptotes represent values where the function is undefined and the function approaches positive or negative infinity as θ approaches these values.

OD. 15
□E. 10

SUBMIT
B. 2 and OD. 15 are not possible lengths for the third side of the triangle.
To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Given that two sides have lengths 6 and 9, we can analyze the possibilities:
6 + 9 > x
x > 15 - The sum of the two known sides is greater than any possible third side.
6 + x > 9
x > 3 - The length of the unknown side must be greater than the difference between the two known sides.
9 + x > 6
x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.
Based on the analysis, the possible values for the length of the third side are:
A. 7
C. 4
□E. 10
O F. 12
B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

Factorise:
A) x^2 + 11x - 26
B) x^2 -5x -24
C) 9x^2 + 6x - 8
Answer:
X^2+(13-2)x -26
x^2+13x-2x-26
x(x+13) -2(x+13)
(x+13) (x-2)
Answer:
Step-by-step explanation
A) To factorize x^2 + 11x - 26, we need to find two numbers that multiply to give -26 and add to give 11. These numbers are 13 and -2. Therefore, we can write:
x^2 + 11x - 26 = (x + 13)(x - 2)
B) To factorize x^2 -5x -24, we need to find two numbers that multiply to give -24 and add to give -5. These numbers are -8 and 3. Therefore, we can write:
x^2 -5x -24 = (x - 8)(x + 3)
C) To factorize 9x^2 + 6x - 8, we first need to factor out the common factor of 3:
9x^2 + 6x - 8 = 3(3x^2 + 2x - 8)
Now we need to find two numbers that multiply to give -24 and add to give 2. These numbers are 6 and -4. Therefore, we can write:
9x^2 + 6x - 8 = 3(3x + 4)(x - 2)
Choose the standard form equation that equals the combination of the two given equations. 07x-y=-5 1 7x+y=5 072-y=5 7x+y=-5 9) Choose the standard form equation that equals the combination of the two given equations. Ox-y=14 7x +3=5 and y-1=6 2- 4y = -14 4x - y = -14 4x - y = -4 42 +5= -4 and y-3=2
The standard form equation that equals the combination of the two given equations, \(07x-y=-5\) and \(7x+y=5\), is \(14x = 0\).
To find the combination of these two equations, we can add them together. When we add the left sides of the equations, we get \(07x + 7x = 14x\). Similarly, when we add the right sides, we get \(-y + y = 0\), and \(5 + (-5) = 0\).
Therefore, the combined equation in standard form is \(14x = 0\).
Regarding the second set of equations provided, \(0x-y=14\) and \(7x + 3 = 5\) and \(y-1=6\) and \(2- 4y = -14\), none of these equations can be combined to form a standard form equation. The first equation is already in standard form, but it does not relate to the other equations given. The remaining equations do not involve both \(x\) and \(y\), and therefore cannot be combined into a single standard form equation.

Maycon had a coupon for 25% off the price of a shirt at a Foot Locker. . On the day he went, the store was also having a sale. The original price of the shirt was $30.75. • The price after the coupon and the additional discount was $20.50. What was the amount of the additional discount Maycon received?
The amount of the additional discount Maycon received is $23.0625 - $20.50 = $2.5625.
To find the amount of the additional discount Maycon received, we first need to calculate the price of the shirt after applying the 25% coupon discount.
The original price of the shirt is $30.75. After applying the 25% off coupon, Maycon would get a discount of 25% of $30.75, which is 0.25 * $30.75 = $7.6875.
So, the price of the shirt after the coupon discount would be $30.75 - $7.6875 = $23.0625.
Now, we know that the final price of the shirt, after both the coupon discount and the additional discount, is $20.50.

5qt= ___ c
Five quarts is equal to twenty cups (5qt= 20 c).
In the US customary system, 1 quart (qt) is equivalent to 4 cups (c). This means that each quart can be divided into 4 equal parts, each representing a cup. To convert from quarts to cups, you need to multiply the number of quarts by the conversion factor of 4. In this case, you have 5 quarts, so by multiplying 5 by 4, you get 20 cups. Therefore, 5 quarts is equal to 20 cups.
This conversion is based on the relationship between the quart and cup units in the US customary system and is commonly used when measuring volumes in recipes and cooking.

B. If ∠A B C ≅ ∠D B E , then ∠A B C and ∠D B E are vertical angles.
If ∠ABC ≅ ∠DBE, then ∠ABC and ∠DBE are vertical angles.
Vertical angles are a pair of non-adjacent angles formed by two intersecting lines. These angles are congruent, meaning they have the same measure. In this case, if ∠ABC ≅ ∠DBE, it implies that ∠ABC and ∠DBE have the same measure and are therefore vertical angles.
Vertical angles are formed when two lines intersect. They are opposite to each other and do not share a common side. Vertical angles are congruent, meaning they have the same measure. This can be proven using the Vertical Angle Theorem, which states that if two angles are vertical angles, then they are congruent.
In the given scenario, ∠ABC and ∠DBE are said to be congruent (∠ABC ≅ ∠DBE). Therefore, according to the definition of vertical angles, ∠ABC and ∠DBE are vertical angles.
