Complementary angles have angles whose sum is 90 degrees. The ‘c’ in complementary angle can be used to form 9 in 90 degrees. Supplementary angles are angles whose sum is 180 degrees. The ‘s’ in supplementary angle can be used to form 8 in 180 degrees. If the intersection of P and Q creates a 71 degree angle, then 90 - 71 = 19 degrees is its complementary angle. Its supplementary angle is 180 - 71 = 109 degrees. The answer is D) The complementary angle is 19 degrees and the supplementary angle is 109 degrees.
