Complementary angles sum up to 90°. If one angle measures 39°, you can find the other angle by subtracting 39° from 90°.
\[ 90° - 39° = 51° \]
So, the other angle measures 51°.
A figure displays two complementary angles. If one of the angles has a measure of 39°, what is the other angle measure?(1 point) Responses 39° 39° 141° 141° 129° 129° 51°
