Answer:
∠EGD
Explanation:
What is an angle?
An angle is a measure of a turn, measured in degrees or °. Angles are made up of two rays, making the sides of the angle.
What is a complementary angle?
Two angles are complementary if their measures add to 90 degrees.
Looking at the picture, we can see that angle ∠EGF and ∠EGD are reflecting angle ∠DGC, meaning that ∠EGF and ∠ EGD add up to 90 degrees, making them complementary.
Therefore, ∠EGD is the correct answer.
