An angle measures 120� less than the measure of a supplementary angle. What is the measure of each angle?
------
angle: x
supplementary angle: 180-x
--------------------------------
Equation:
x = (180-x)-120
2x = 60
x = 30 degrees
180-x = 150 degrees
-------------------

Let the angle = x
x measures 120 less than 180-x

Subtract

Add x to both sides

Divide both sides by 2
