55. In the figure below, AB is parallel to DE, the measure of ∠ABC is 49°, and the measure of ∠BCD is 137°. What is the measure of ∠CDE ?

Answer and Explanation

Your Answer is

Correct Answer is D

Explanation

Through the point C, draw a straight line parallel to the straight lines AB and DE. Let any point on the line and above point C be F. So the angle FCB=49 degrees, and the angle DCF=137-49=88 degrees. So the angle D=180-137=92 degrees.
