Responses

120°
and 90°
120 degrees and 90 degrees

120°
and 17°
120 degrees and 17 degrees

17°
and 73°
17 degrees and 73 degrees

73°
and 34°

Answer 1

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

Let's check the angle pairs:

1. 120° and 90°: 120 + 90 = 210 (not complementary)
2. 120° and 17°: 120 + 17 = 137 (not complementary)
3. 17° and 73°: 17 + 73 = 90 (complementary)
4. 73° and 34°: 73 + 34 = 107 (not complementary)

The pair that corresponds to complementary angles is 17° and 73°.
