Question

If a and b are supplementary and m a = 37°45', then m b = ______. 142°55' 52°15’ 52°55’ 142°15'

Answer 1

If ∠A and ∠B are supplementary and m∠A = 37°45', then m∠B = ______.

142°55'

52°15’

52°55’

142°15'

Explanation:

Answer 2

a + b = 180° = 179° 60';
We have a = 37°45';
Then b = 179° 60' - 37°45' = 142°15';
The last answer is the correct answer!
