Question

4 times the complement of an angle is equal to its supplement find the angle

Answer 1

Find the angle whose supplement is four times its complement

Supplementary angles add to 180 degrees, so the supplement of angle x is 180 - x. Complementary angles add up to 90 degrees, so the complement of x is 90-x. Supplement is 120, complement is 30, 120 is four times 30.
