A figure displays two complementary nonadjacent angles. If one of the angles has a measure of 39°, what is the other angle measure?(1 point)

Since the angles are complementary, their measures add up to 90°.

Let the measure of the other angle be x°.
Then we have the equation x + 39 = 90.
Subtracting 39 from both sides, we get x = 51.
Hence, the other angle measures 51°. Answer: \boxed{51}.
