first one is easy money
right angle = 90, and we also have 42 so:
90+42=132
180-132=48
2nd one is weird, why is there a 150 down there? triangles add up to 180 nso right angle already gets 90 degrees.--oh wait I just got it, so that is the angle of the outer. we know a line is 180 degrees, so 180-150=30 so we found that degree
So now 90+30=120, 180-120=60
