supplementary angles add up to 180°, while complementary angles add up to 90°. to find the supplementary angle to 83° just subtract it from 180°.

180 - 83 = 97°

to find the complementary angle, just subtract 65° from 90°.

90 - 65 = 25°

97° is the answer to Part A, and 25° is the answer to Part B. hope this helps!
