Give that angle x q r equals 180° and angle lqm equals 180°, which equation could be used to solve problems involving the relationship between angle x q m and angle r q m? A 180° + 140 - 7 A = 70 - 3 ab 180 + 70 - 3 8 = 140 - 78 c 180 - 140 - 7/8 = 70 - 3/8 d 140 - 7/8 - 70 - 3/8 = 180 e360 - 140 - 78 = 70 - 3A
