Answer:
These triangles cannot be proven congruent
Step-by-step explanation:
If all sides and angles of a triangle is congruent to the corresponding sides and angles of another triangle, both triangles are congruent to each other.
This means, they have the same shape and size.
Invariably, knowing just the angles of two triangles are congruent to each other, is not enough to prove that the two triangles are congruent to each other.
Two triangles might have the same angle measure but different size lengths. This means they can have the same shape but different size.
With the information given in the diagram, we can only say that both triangles are similar to each other. However, we cannot prove they are congruent to each other.

Answer:
y - 13 = -2(x+7)
Step-by-step explanation:
Given
Coordinate point (-7, 13)
Slope m = -2
We can express the euation of the line in point slope form as shown;
The point slope form of the equation is expressed as;
y - y0 = m(x-x0)
x0 = -7, y0 = 13 and m = -2
Substitute;
y - 13 = -2(x-(-7))
y - 13 = -2(x+7)
Hence the required equation in point- slope form is y - 13 = -2(x+7)

Tara wants to attend a four-year college to become a math teacher. Which statements explain the possible differences in total yearly cost for attending a public college in state and public college out of state? Check all that apply.
A - A public college out of state will have fewer transportation costs than a public college in state.
B - A public in-state college charges less for in-state tuition than for out-of-state tuition.
C - Books and fees will generally cost more at a private college than a public college.
D - Tara will most likely have to pay room and board expenses at an out-of-state public college, but might be able to commute to a public college in state.
E - All the extra fees besides tuition are different for in-state and out-of-state public colleges.
Answers
- A public in-state college charges less for in-state tuition than for out-of-state tuition.
- Tara will most likely have to pay room and board expenses at an out-of-state public college, but might be able to commute to a public college in state.
Explanation:
If Tara wants to study out of state she could face higher tuition costs; public universities generally favor their residents with lower tuition costs, contrary to the charge for students who comes from other states.
Also, if she wants to study outside the state, Tara would have to analyze the costs of a residence and food that she will have to cover if she studies outside the state. On the contrary, if she studies in the state she could live with her family and only cover the transportation costs.

Answer:
x = 35°
y = 55°
Step-by-step explanation:
60° + 50° + 2x = 180° (Sum of angles on a straight line is 180°)
2x = 180° - 110°
x = 70°/2 = 35°
2x + 2y = 180°( Sum of interior angles of a triangle is 180°)
2× 35° + 2y = 180°
70° + 2y = 180°
2y = 180° - 70°
y = 110°/2
y = 55°

we conclude that:
The value of missing x = 6The value of missing y = 21Step-by-step explanation:
Given that the table represents a linear function, so the function is a straight line.
Taking two points
(-12, 17)(-10, 19)Finding the slope between (-12, 17) and (-10, 19)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-12,\:17\right),\:\left(x_2,\:y_2\right)=\left(-10,\:19\right)[/tex]
[tex]m=\frac{19-17}{-10-\left(-12\right)}[/tex]
[tex]m=1[/tex]
Using the point-slope form to determine the linear equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 1 and the point (-12, 17)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 17 = 1 (x - (-12)[/tex]
[tex]y - 17 = x+12[/tex]
[tex]y = x + 12+17[/tex]
[tex]y = x+29[/tex]
Thus, the equation of the linear equation is:
[tex]y = x+29[/tex]
Now substituting x = -8 in the equation
[tex]y = x+29[/tex]
[tex]y = -8+29[/tex]
[tex]y = 21[/tex]
Thus, the value of missing y = 21 when x = -8
Now substituting y = 23 in the equation
[tex]y = x+29[/tex]
[tex]23 = x+29[/tex]
[tex]x = 29 - 23[/tex]
[tex]x = 6[/tex]
Therefore, the value of missing x = 6 when y = 23
Hence, we conclude that:
The value of missing x = 6The value of missing y = 21Answer:

If the 4th and 7th terms of a G.P are −1/2 and
− 4, respectively, then find G5 and S6 .
Answers
Answer:
G5 = -1
S6 = -63/16
Step-by-step explanation:
The formula for finding the nth term of a GP is Tn = ar^n-1
a is the first term
r is the common ratio
n is the number of terms
If the 4th term is -1/2
T4 = ar^4-1
T4 = ar³ = -1/2.... 1
If the 7th term is -4
T7 = ar^7-1
T7 = ar^6 = -4.... 2
Divide both equation
ar^6/ar³ = -4/(-1/2)
r³ = -4×-2
r³ = 8
r = 2
Common ratio is 2
Since ar³ = -1/2
a(2)³ = -1/2
8a = -1/2
a = -1/16
The first term is -1/16
Get the fifth term G5
G5 = ar⁴
G5 = (-1/16)(2)⁴
G5 = (-1/16)(16)
G5 = -1
Get the sum of the first six terms S6
S6 = a(r^n-1)/r-1
S6 = -1/16(2^6-1)/2-1
S6 = -1/16(64-1)
S6 = -63/16
Hence the sum of the first six terms is -63/16
