Question

Two angles are supplementary the measure of one angle is 4 times the measure of the other angle what is the measure of the smaller angle

Answer 1

X + y = 180
x = 4y 
Plug that in and you get: 4y + y = 180
5y = 180
y = 36

If you want the larger angle, simply plug in y to x = 4y
So: x = 4(36) = 144

The smaller angle is 36 degrees, and the larger angle is 144 degrees.
