Angle x is (2n+12) and angle y is (3n+18). find the measure of angle x

X and Y are supplementary angles. The sum of the supplementary angles is 180.

So, X + Y = 180
180 = 2n+12 + 3n + 18
180 = 5n + 30
5n = 150
n = 30

X = 2n+12
X = 2(30) + 12
X = 72

Y = 3n + 18
Y = 3(30) + 18
Y = 108

The only number less than 8 that can equal 12 would be 6, 36 is the dividend
