Answer:

A, 74°

Explanation:

Both of the angles are named y, so this means they are the same/have the same value!

Remember, all triangles equal 180°

To find y...

First, we subtract 32° from 180° to see what the Y angles total up to!

180° - 32° = 148°

the two y angles on the left side of the triangle equal 148°, but what does just one of them equal?

Divide by 2 to find out!

148° ÷ 2 = 74°

one y angle = 74°

y = 74°
