The mangle6 = (11x - 8)² and mangle7 = (12x - 4)². 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 uppercase left: 2, 4, 3, 1. On line y, where it intersects with line w, 4 angles are created, labeled clockwise, from uppercase left: 6, 8, 7, 5. What is the measure of angle4?
A) m∠4=40°
B) m∠4=48°
C) m∠4=132°
D) m∠4=140°
