Answer:
- complement: 67°
- supplement: 157°
Explanation:
You want the complement and supplement of the angle 23°.
Complement
An angle and its complement total 90°. Let c represent the complement of the angle. Then we have ...
c + 23° = 90°
c = 90° -23° = 67°
The complement of the angle is 67°.
Supplement
An angle and its supplement total 180°. Let s represent the supplement of the angle. Then we have ...
s + 23° = 180°
s = 180° -23° = 157°
The supplement of the angle is 157°.
