Answer:

the answer would be 67 and 23.

Step-by-step explanation:

Complementary angles are angles that add up to measure 90 degrees.

lets say angle one is y.

angle two would be 2y + 21.

so, 90 = y + 2y + 21. Group like terms to get 90= 3y +21.

subtract 21 from both sides 69=3y

divided both sides by three 23=y

so angle one is 23, and if you plug in 23 for y in angle two's equation you get 67.
