What is the measurement of angle X, angle Y, and angle Z?

Angle x= 95 because you would subtract 50 and 45 from 180 and then subtract that number from 180 again, since angle x is supplementary to the other angle.
Angle z= 128 because it’s supplementary so 180-52= 128
Angle y= 180-33= 147 because you would add both angles x and z and then subtract that from 180 to get the missing angle. Then you would subtract that missing angle from 180 since it’s supplementary with angle y, and that is how you find angle y.
