Question

If the supplement of an angle is three-times if its complement, then find the angle.

1. 50°
2. 100°
3. 60°
4. 45°

Answer 1

Given that supplement of angle =180 –x and complement of angle =90-x , hence acc to sum in the fine manner.

180-x=3(90-x)

180-x=270-3x

-x =3x=270-180

2x=90

X=90/2

X=45
