120 and 90

120 and 17

1 answer

Complementary angles are two angles that add up to 90 degrees.

Let's check the pairs:

  • 73 and 34: 73 + 34 = 107 (not complementary)
  • 120 and 90: 120 + 90 = 210 (not complementary)
  • 17 and 73: 17 + 73 = 90 (complementary)
  • 120 and 17: 120 + 17 = 137 (not complementary)

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