X=7
y=8 (I think) GOOD LUCK :)
The picture includes solving for x and the angle measurement for all. Since angle 2 and 7 are equal you able to set those equations equal to each other to solve for x. Then plug the x value in to find the exact amount for the angle. Next you subtract that value from 180 to find the other value of angles.
