A figure displays two complementary nonadjacent angles. If one of the angles has a measure of 39 degree, what is the other angle measure?

____degree

1 answer

Complementary angles add up to 90 degrees. If one angle has a measure of 39 degrees, then the other angle measure can be found by subtracting 39 from 90:

90 - 39 = 51

The other angle measure is 51 degrees.
