The m∠6 = (11x - 8)° and m∠7 = (12x - 4)°. Parallel lines x and y are cut by transversal W. On line x where it intersects with line W, 4 angles are created. Labeled clockwise, from upper left, the angles are: 2, 4, 3, 1. On line y where it intersects with line W, 4 angles are created. Labeled clockwise, from upper left, the angles are: 6, 8, 7, 5. What is the measure of angle 4?
a) m∠4 = 40°
b) m∠4 = 48°
c) m∠4 = 132°
d) m∠4 = 140°
