Which of the following are measures of complementary angles? a. 50° and 41° b. 100° and 80° c. 77° and 13° d. 35° and 10°

Two angles are complementary when they add up to 90°

then, doing all the options:

A) 50° + 41° = 91°, so this angles are non complementary.

B) 100° + 80° = 180°, so this aren't complementary, but they are Supplementary (because their addition is 180°) angles.

C) 77° + 13° = 90°, si this angles are complementary

D) 35° + 10° = 45°, this pair is not complementary.

So the only correct answer is C.

i think da answer is

d.square root of 3
