Answer:
the answer would be 67 and 23.
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.
