Complementary angles are two angles whose measures add up to 90 degrees.
Let's check each of the pairs:
-
17° and 73°: \( 17 + 73 = 90° \) (Complementary)
-
120° and 17°: \( 120 + 17 = 137° \) (Not complementary)
-
73° and 34°: \( 73 + 34 = 107° \) (Not complementary)
-
120° and 90°: \( 120 + 90 = 210° \) (Not complementary)
Therefore, the two angle measures that correspond to complementary angles are 17° and 73°.
