A transversal line cuts two horizontal parallel lines. About the point of intersection of the top parallel line and the transversal line is the exterior right angle, 5x + 11 degrees. About the point of intersection of the bottom parallel line and the transversal line are 2 given angles: interior, left, 119 degrees and interior, right, y degrees.
