Lines e and f are parallel. the mangle9 = 80° and mangle5 = 55°. parallel lines e and f are cut by transversal c and d. all angles are described clockwise, from uppercase left. where lines e and c intersect, the angles are: 1, 2, 4, 3. where lines f and c intersect, the angles are 5, 6, 8, 7. where lines e and d intersect, the angles are 9, 10, 12, 11. where lines f and d intersect, the angles are 13, 14, 16, 15. which angle measures are correct? select three options
