Answer:
(A) 24 and 66
Step-by-step explanation
Complementary angles add up to 90 degrees
Supplementary angles add up to 180 degrees
(A) 24 + 60 = 90
These 2 angles sum to 90, so therefore they are complementary
(B) 56 + 124 = 180
These 2 angles sum to 180, so they are supplementary, not complementary
(C) 34 + 66 = 100; 34 + 56 = 90
While 34 and 56 sum to 90 degrees, 34 and 66 sum to 100, so this answer does not satisfy the question
(D) 56 + 124 = 180; 66 + 114 = 180
Both of these angle pairs are supplementary, so they do not satisfy the answer to the question
