Parallel lines u and v are cut by a transversal t. Find the measure of the angle if… There are corresponding angles measuring 90 degrees and (4x + 2) degrees. There are alternate interior angles measuring (6x + 10) degrees and (5x + 50) degrees. There are alternate exterior angles measuring (9y - 3) degrees and (6y + 12) degrees. Sketch ALL three examples. Be sure to sketch them so that obtuse, right and acute angles are accurately shown.
