Question

Find the supplementary angle of
(i) 70º (ii) 35º (iii) 165º (iv) 90º (v) 0º
(vi) 180º (vii) 95º

Answer 1

two angles are supplementary when their sum is 180°

so to find supplementary angle of the given angle you just have to subtract that given angle from 180

1 ) 70°

180- 70 = 110°


2) 35 °

180 - 35 = 145°

3) 165 °

180 - 165 = 15°

4) 90°

180 - 90° = 90 °

5) 0°

180 - 0 = 180°


6) 180°

180- 180 = 0°

7) 95°

180 - 95 = 85°

hope this helps you
