Question

The sum of the measures of two complementary angles

Answer 1

Answer:

The angles are 23° , 67°

Step-by-step explanation:

Let one angle be 'x'.

Its complement = 2*x + 21 = 2x + 21

x + 2x + 21 = 90°

     3x  + 21 = 90

Subtract 21 from both sides,

              3x = 90 - 21

              3x = 69

Divide both sides by  3,

                 x = 69/3

                 x = 23°

Its complement = 2*23 + 21

                          = 46 + 21

                          = 67°

Two complementary angles are 67 and 23
