Parallel lines t and u are cut by two transversals, r and s, which intersect line u at the same point. Parallel lines t and u are cut by 2 transversals, 4 and s, which intersect line u at the same point. Clockwise from top left, the angles formed with lines r and t are (3 x + 17) degrees, blank, blank, blank; formed with lines s and t are blank, blank, blank, 46 degrees; formed with lines r, s, and u are blank, blank, blank, (4 x minus 8) degrees, 2, 1. What is the measure of angle 2?
