Question

find the angle whose supplement is four times it's complement

Answer 1

Let the angle be x.

We know that, supplement of an angle= 180-x

Complement =90-x
Supplement = 4(complement)

or, 180-x = 4 (90-x)
or, 180-x = 360-4x
or, 3x = 180
or, x = 60

Hence, the angle is 60.
Supplement =120
Complement=30.
