Find the angles B and D of the trapezoid ABCD with the bases AD and BC, if you know that the angle A = 42 degrees and the angle C is 110 degrees
The sum of the angles of the trapezoid at the side is 180.
Then the angle B = 180 – A = 180 – 42 = 138.
Angle D = 180 – C = 180 – 110 = 70.
Answer: Angle B is 138, Angle D is 70.
