Supplementary angles add up to 180 degrees.
2x - 8 + 8x - 12 = 180
10x - 20 = 180
10x = 200
x = 20
Angle 1 = 32
Angle 2 = 148
The measure of the largest angle is 148

-9(x) = -117
Solve for "a number" (x). Isolate it. Note the equal sign. What you do to one side, you do to the other. Divide -9 from both sides.
-9x/-9 = -117/-9
x = -117/-9
x = 13
13 is your answer
hope this helps
The mean is four
