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°.
