With a figure with 1 pair of parallel sides and 2 right angles, and the third angle is 52 degrees, what is the measure of the fourth angle?

The inside has to equal 360 since its a 4 sided figure
you know 2 sides which are 90
and the third side is 52
so
360= 52 + 90 + 90 + x
solve for x
360  90  90  52 = x
x=128
