One angle is four times as large as its supplement. What is the measure of the smaller angle
.
Let x = angle
180-x = supplement of angle
.
From: "One angle is four times as large as its supplement."
x = 4(180-x)
x = 720-4x
5x = 720
x = 720/5
x = 144
.
Supplement:
180-x = 180-144 = 36 degrees (answer)
