List everything that you can understand about that figure:
x=y+30; x+y+z=180; 30=y;
Do you understand the reasons for those?
Exterior angle of a triangle...; three supplementary angles; two equal sides & angles, isosceles triangle. Note the way some segments are designated for congruency.
Those three equations are enough to solve for each variable without complications.
