Question

What is the measure of _Y, in degrees?

y
A. 116°
B. 32°
C. 640
D. Cannot be determined

Answer 1

C. 116º

Explanation:

Both sides are congruent, so the triangle is an isosceles triangle. So angle Z will have to be congruent to angle X. Add together the two angles, (32 + 32) and subtract the sum from 180º since all triangles add up to 180º.

32 + 32 = 64

180 - 64 = 116
