Two lines intersect to form two pairs of vertical angles.Angle 1 with measure (20x + 7) degrees and angle 3 with measure (5x + 7y + 49) degrees are vertical angles. Angle 2 with measure (3x - 2y + 30) degrees and angle 4 are vertical angles.Find the values x and y and the measure of all four angles.
