Math Problem Statement
Which angle is complementary to ∠4?
Solution
In this problem, we are asked to find which angle is complementary to ∠4. Complementary angles are two angles whose measures add up to 90 degrees.
From the diagram:
- ∠4 and ∠5 appear to be adjacent angles, and they form a right angle, which makes them complementary. Therefore, ∠5 is complementary to ∠4.
Thus, the correct answer is ∠5.
