Imagine this is a set of lines in the form of an x. 1. On one side of the x you have (11x-37)° 2. And on the other side of the x you have (7x+27)° Now... Find the measure of each marked angle. |dw:1327300660128:dw|

|dw:1327301528168:dw| That wording might have made it a bit hard to understand with the 1 and 2 acting as variables. x + a = 180 ; supplementary angles on a line x + b = 180 ; supplementary angles on a line a = 180 - x b = 180 - x easier to see that they are equal. So set your two angles equal and solve 11x-37 = 7x+27

I had to do something wrong I got (11x-37)°=(7x+27) -7x+37 -7x+37 4x=64 /4 /4 x=16 But when plugged in I get two different numbers. (11(16)-37) = 140° and (7(16)+27) = 139°
