Question

Find the following:

The angles whose supplement is four times its complement.

Answer 1

SUPPLEMENTARY ANGLE = 180
180-160 = 20
160/4 = 40
40*4 = 160

Answer 2

Let the angle = x
Complement = 90 - x
Supplement = 180 - x
ATQ     180 - x = 4(90 - x)
           180 - x = 360 - 4x
           3x = 180
           x = 60°
So. the angle = 60°
