Two angles are complementary to each other. If one angle measures 19.75°, what is the degree measure of the other angle?
a 19.75°
b 39.5°
c 70.25°
d 160.25°
Since two angles are complementary, their measures add up to 90°.
Let the measure of the other angle be x.
19.75° + x = 90°
Subtracting 19.75° from both sides:
x = 90° - 19.75°
x = 70.25°
The degree measure of the other angle is 70.25°. Therefore, the answer is choice c) 70.25°.
