Classify the following triangle as acute, obtuse, or right.
OA. Obtuse
OB. Acute
OC. Right
OD. None of these

The triangle is an acute triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of angles of the triangle are

The measure of ∠ABC = 50°

The measure of ∠BAC = 50°

The measure of ∠ACB = 80°

So , all the angles of the triangle are less than 90°

So , it is an acute triangle

Hence , the triangle is acute

PLZZZ HELPPP Read the excerpt from "The New Marvel in Photography" by H. J. W. Dam.

In all the history of scientific discovery there has never been, perhaps, so general, rapid, and dramatic an effect wrought on the scientific centres of Europe as has followed, in the past four weeks, upon an announcement made to the Würzburg Physico-Medical Society, at their December meeting, by Professor William Konrad Röntgen, professor of physics at the Royal University of Würzburg. The first news which reached London was by telegraph from Vienna to the effect that a Professor Röntgen, until then the possessor of only a local fame in the town mentioned, had discovered a new kind of light, which penetrated and photographed through everything. This news was received with a mild interest, some amusement, and much incredulity; and a week passed. Then, by mail and telegraph, came daily clear indications of the stir which the discovery was making in all the great line of universities between Vienna and Berlin. Then Röntgen's own report arrived, so cool, so business-like, and so truly scientific in character, that it left no doubt either of the truth or of the great importance of the preceding reports. . . .

Exactly what kind of a force Professor Röntgen has discovered he does not know. As will be seen below, he declines to call it a new kind of light, or a new form of electricity. He has given it the name of the X rays.

The central idea of this excerpt is developed through

Kira wants to graph y = -3(x + 1)(x - 3). They think that it will be a
downward-opening parabola. They think that it has x-intercepts at (1, 0)
and (-3, O). They think that the axis of symmetry, or x-coordinate of the
vertex, will be halfway between 1 and -3, or -1. They substitute that into
their function, and get a y-coordinate of O. So, they graph their work, and
get what is shown. Explain whether you agree or disagree with Kira's work,
and if you disagree, what you think should be done differently. Answer
specifically about x-intercepts, the midpoint and axis of symmetry, and
vertex of the graph.
