Answer: y = 120 degrees, x = 31 degrees

Step-by-step explanation:

Y is 120 degrees because same-side exterior angles are supplementary.

Therefore, 60+ y = 180; y = 120

Since "y" and "4x-64" are supplementary, they add up to 180.

We already know y as 120.

So 120 + 4x - 64 = 180

4x = 124

x = 31
