Let x= measure of angle 1 Let y= measure of angle 2
This is solving a system of equations
3x=30+ 5y which can also be written
3x-5y=30, and
2x+2y=180 There are a few ways to solve this, like solving for x in one of the equations and plugging it in for x in the other equation, but here is another way: 2(3x-5y)=2*30 3(2x+2y)= 3*180
6x-10y=60 6x+6y=540, and now subtract to get rid of x 0-16y=-480 Y=30 Plug it back in to either equation and you get x=60
