Question

∠a and ∠b are complementary angles. ∠a measures 24∘. What is the measure of ∠b?

Answer 1

66°

Explanation:

Complementary angles are those that add up to 90 degrees. Since a and b are complementary, we can write:

∠a + ∠b = 90

We already know that ∠a = 24°, so we can plug this in:

24 + ∠b = 90

∠b = 90 - 24 = 66°

Thus, the answer is 66°.
