Step-by-Step Solution
Complement = 90 − 35 = 55°. Supplement = 180 − 35 = 145°. Sum = 55 + 145 = 200°.
Answer: A) 200
The measure of an angle is 35°. What is the measure of its complement plus its supplement (in degrees)?

Key idea: Complementary and supplementary
Two angles are **complementary** if they add to 90°. So if one is 35°, the complement is 90° − 35° = 55°.
Two angles are **supplementary** if they add to 180°. So if one is 110°, the supplement is 180° − 110° = 70°.
The angles don't have to be next to each other — only their measures matter.
Two angles are **supplementary** if they add to 180°. So if one is 110°, the supplement is 180° − 110° = 70°.
