Processing Complementary and Supplementary Angles

For each problem, write an algebraic equation and then solve.

1. Two angles are complementary. If one angle measures 4x + 3 and the other angle

measures 2x + 21, find the measure of each angle.

2. An angle measures 2x + 7 and its supplementary measures 3x – 17. Find the measure of

each angle.

3. An angle measures 4x + 3 and its supplementary measures 5x + 6. Find the measure of

each angle.

4. An angle measures 7x – 13. Its complement measures 4x + 15. Find the measure of

each angle.
