Question

The figure shows two parallel lines AB and CD cut by transversals EF and GH. Angle EKD measures 90 degrees.

AB is parallel to CD. EF and GH are transversals that cut CD at the same point. The angle between the transversals at the point where they meet CD is 50 degrees. GH makes an angle x with AB. EF is perpendicular to AB and CD.

What is the measure of angle x?
35 degrees 40 degrees 45 degrees 50 degrees
