The ratio of the vertex angle to either of the base angles in an isosceles triangle is 5: 2. determine the measure of the vertex angle. show how you arrived at your answer

100 degrees.

Step-by-step explanation:

The total representation of the triangle's base angles is 5:2:2.

The amount that has to be multiplied by is x for each of the angles.

5x + 2x + 2x = 180     Add the like terms

9x = 180                     Divide by 9

x = 180/9                    Divide

x = 20

The angles are

Vertex angle = 5*20 = 100

One of the equal angles = 2*20 = 40

The other equal angle = 2 * 20 = 40

step-by-step explanation:

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
