Find the measure of the exterior angle.

Answer:
x=52°
Step-by-step explanation:
All triangles equal to 180
180-90 (square represents 90°)
90-38=52°
Answer: 128°
Step-by-step explanation:
The exterior angle which is marked here as x is equal to the two opposite/ non adjacent interior angles which are mentioned in the given figure
Let the exterior angle be x
As you the see the interior angles (inside the triangle) are 90° and 38°
So,
x = 90+38 (sum)
= 128°
