Question

Find the measure of the exterior angle.

Answer 1

The answer to this is128

Answer 2

128 degrees

Explanation:

All the angles in a triangle will add up to 180 degrees.

38 + 90 + y = 180

128 + y = 180

y = 52

Two angles lying on a line next to each other will form a 180 degree angle so

x + 52 = 180

x = 128
