Question

Which angles are complementary? I'm not sure if its B.

Answer 1

The answer is B. the measure of angle GPF and the measure of angle GPH.

Explanation:

Two angles are called complementary when their measures add to 90 degrees.

Since the measure of angle FPD has a known angle measure of 90 degrees, the measure of angle FPH is also 90 degrees.

Thus, causing the measure of angle GPF and the measure of angle GPH to add up to 90 degrees, which makes the two angles complementary.

Answer 2

You are right, it's B

Explanation:

Complementary angles are angles that add up to 90 degrees.
