Answer: 30° and 60°, see attached for picture.
Explanation:
Complement angles are angles that add up to 90 degrees. We can create an equation knowing that one is twice the other. Let x be the smaller angle.
Given:
x + 2x = 90°
Add like terms:
3x = 90°
Divide both sides by 3:
x = 30°
Substitute to find the larger angle:
2x = 2(30) = 60°
The angles are 30° and 60°. I have also drawn a picture of this attached below.
