In a rectangular trapezoid, one angle is 110 degrees, find the rest of the corners.

In a trapezoid, the degree measures of the angles adjacent to the lateral side always add up to 180 degrees. So, as a rectangular trapezoid is given, so if one angle is 90 degrees, and the second angle adjacent to the same side is 90 degrees. Knowing the obtuse angle C from the second pair of corners adjacent to one side, we find an acute angle:

D = 180 – C = 180 – 110 = 70 (degrees).

Angle A = 90 (degrees), angle B = 90 (degrees).
