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
