Answer:
c. 68, 112
Step-by-step explanation:
The angle is our unknown, so we will call it x. If the angle is x, then its supplement is 180 - x (supplementary angles add up to equal 180). The word "is" means "equals", so putting the equation together looks like this:
180 - x = 2x - 24. Add x to both sides and at the same time add 24 to both sides (combining like terms, in other words):
204 = 3x so
x = 68
x is the angle measure, so the angle is 68 and its supplement is 180 - 68 = 112
