An angle measures 50° more than the measure of its supplementary angle. What is the measure of each angle?

Step-by-step explanation:

Let angle x and angle y be the supplementary angles.

Because both angles are supplementary, we know that:

x+y=180

It also tells us that the greater angle (which we will assume as x) is 50 degrees greater, thus:

x-y=50

Solving both equations we get x=115 and y=65.

Therefore the two angle measures are 115 and 65 degrees.

7 - 9 = -2

reversed:

-2 + 9 = 7
