Step-by-step explanation: Because x and w are parallel the angle at 4 will be the same as the angle below that is 75°. Angle 3 is going to make 180° with angle four so angle 3 is 180-75=105. Because angle 3 is directly across from 1 they're the same so m1 = 105°. M2 will be the same as 4 so it is 75°.
