A figure consists of five angle measures: 17°, 34°, 90°, 120°, and 73°. Which two angles measures correspond to complementary angles?(1 point)

Question

A. 17° and 73°

B. 120° and 90°

C. 120° and 17°

D. 73° and 34°

Answer 1

Complementary angles are two angles whose measures add up to 90 degrees.

Let's check the combinations of the given angles to find the pair that adds up to 90°:

• A. 17° + 73° = 90° (This is complementary)
• B. 120° + 90° = 210° (Not complementary)
• C. 120° + 17° = 137° (Not complementary)
• D. 73° + 34° = 107° (Not complementary)

The correct answer is:

A. 17° and 73°
