Question

Can someone please help me find the measure of the exterior angle.

Answer 1

128 degrees.

Explanation:

Simply add 38 degrees with 90 degrees.

(the square in the corner means 90 degrees)

Answer 2

X=128°

Explanation:

Because an exterior angle of a triangle is equal to of the two opposite interior angle.

The sum of the exterior and interior angle is equal to 180°

In this case the part marked red = 90° because is a right angled triangle.

90+38=128

180- 128=52

180- 52=128

x=128.
