❇️Find the complements of the following angles.

To determine the complementry angle we have to subtract the number with 90°.

(a)45°

- ️90° - 45° = 45°

So the complementry angle of 45° is 45°

(b)8°

- 90° - 8° = 82°

So the complementry angle of 8° is 82°

(c)20°

- 90°- 20° = 70°

So the complementry angle of 20° is 70°

(d)85°

- 90°- 85° = 5°

So the complementry angle of 85° is 5°

(e)13°

- 90°- 13° = 77°

so the complementry angle of 13° is 77°

(f)25°

- 90°- 25° = 65°

So the complementry angle of 25° is 65°

(g)78°

- 90°- 78° = 12°

So the complementry angle of 78° is 12°

(h)43°

- 90°- 43° = 47°

So the complementry angle of 43° is 47°

(i)18°

- 90° - 18° = 72°

so the complementry angle of 18° is 72°

(j)4°

- 90° - 4° = 86°

So the complementry angle of 4° is 86°

☣️Find the supplements of the following angles:-

To determine that the angle is supplementary we have ro subtract it from 180°.

(a)50°

- 180° - 50° = 130°

so the supplementary angle of 50° is 130°

(b)150°

- 180° - 150° = 30°

so the supplementary angle of 150° is 30°

(c)105°

- 180° - 105° = 75°

so the supplementary angle of 105° is 75°

(d)73°

- 180° - 73° = 107°

so the supplementary angle of 73° is 107°

(e)128°

- 180° - 128° = 52°

so the supplementary angle of 128° is 52°

(f)140°

- 180° - 140° = 40°

so the supplementary angle of 140° is 40°

(g)169°

- 180° - 169° = 11°

so the supplementary angle of 169° is 11°

(h)100°

- 180° - 100° = 80°

so the supplementary angle of 100° is 80°

(i)106°

- 180° - 106° = 74°

so the supplementary angle of 106° is 74°

(j)29°

- 180° - 29° = 151°

so the supplementary angle of 29° is 151°
