Question

(a) An angle measures 64°. What is the measure of its complement?

(b) An angle measures 145º. What is the measure of its supplement?

Answer 1

(a) 26 degrees

(b) 35 degrees

Explanation:

(a) complementary angles add up to 90 degrees, therefore the complementary angle to 64 degrees would be 90 - 64, or 26 degrees.

(b) supplementary angles add up to 180 degrees, therefore the supplementary angle to 145 degrees would be 180 - 145, or 35 degrees.
