Question

Right triangle ABC is similar to triangle XYZ. If the measure of angle C is 36", what is the measure of angle Y?​

Answer 1

A. 54

Explanation:

Similar triangles have the same angle measurements. Solve angle B using the fact that all the angles in a triangle add up to 180:

B = 180-36-90 = 54

Therefore, because the triangles are similar, angle Y is also 54.
