Which of the following are measures of supplementary angles? A. 89° and 1° B. 60° and 90° C. 90° and 180° D. 110° and 70°

D is the answer since supplementary angles are two angles that sum up to 180. Since 110 + 70 = 180, D is the right answer.

D.

Supplemtary means that two angles added together = 180°

A fits the definition of a complementary angle. (two angles added together to make 90°)

B = 150°

C = 270°

D = 110 + 70 = 180
