In the diagram, PW is parallel to QX, S and T lie on QX, and U and V are the points of intersection of PW with SR and TR, respectively. If angle SUV = 120 degrees and angle VTX = 112 degrees, what is the measure of angle URV?
Same, where is the diagram, the question is talking about. Using a diagram to solve a problem is very useful, especially when it's given with the problem...
