Question

Find the supplementary angle of

(i) 70°

(ii) 35°

(iii) 165°

(iv) 90°

(v) 0°

(vi) 180°

(vii) 95°

Answer 1

How far we should go in the same direction to reach the straight angle (180°) is called supplementary angle.

(i) Supplementary angle of 70° = 180° – 70° = 110°

(ii) Supplementary angle of 35° is 180° – 35° = 145°

(iii) Supplementary angle of 165° is 180° – 165° = 15°

(iv) Supplementary angle of 90° is 180° – 90° = 90°

(v) Supplementary angle of 0° is 180° – 0° = 180°

(vi) Supplementary angle of 180° is 180° – 180° = 0°

(vii) Supplementary angle of 95° is 180° – 95° = 85°
