Find the missing angle measures in the trapezoid.

Question

angle D= 128 degrees

that is the only number given 

 

It want you to find Angle Measurement A and R

Answer 1

Then it must be an isosceles trapezoid or else we're at a dead end.

 

That would make the base angle 180 - 128 = 52.

 

Same for the other two angles.
