Question

Find the supplementary angle.
4. 80°
5. 65°
34°​

Answer 1

Note that the measurement of the supplementary angles when combined will equal 180°. To find the other angle, simply subtract the angle measurement given from 180:

4. 80°

180 - 80 = 100°

100° is the supplementary angle.

5. 65°

180 - 65 = 15°

15° is the supplementary angle.

6. 34°

180 - 34 = 146°

146° is the supplementary angle.
