Since it's isoceles,
2A%2B2%28138%29=360
2A%2B276=360
2A=84
highlight%28A=42%29
Two angles are 42 degrees, two angles are 138 degrees.

Since the trapezoid is isosceles, the angle on the upper right 
is also 138°.

The lower left angle is supplementary to 138°, so it is 180°-138°
or 42°.

Since the trapezoid is isosceles, the angle on the lower right 
is also 42°.
