18 is the complementary angle. Now find the supplementary angle.
18 + X = 180

let the angle be x
then its complement is 90-x
x = 4(90-x)
x = 360 - 4x
5x = 360
x = 72
so the angle is 72°
and its supplement is 180-72 = 108°
our angle = 72
its complement = 18
is the angle 4 times its complement ?
is 72 = 4(18) ? yes
