Final answer:
The measure of the complementary angle to one that measures 83° is 7°, as complementary angles always add up to 90°.
Step-by-step explanation:
If the measure of an angle is 83°, then the measure of its complementary angle can be found by subtracting the given angle's measure from 90°, since the sum of complementary angles is always 90°. Therefore, the measure of the complementary angle is 90° - 83° = 7°.
