Answer: M<1 = 45, M<2 = 135, m<4 = 45
Explanation:
Angles such as 1 to 4 and 2 to 3 have the same angle, so you take the total of 3 and 2 (270) and subtract it from 360 to to get the values of angles 1 and 4 combined. divide this in half to separate the two angles to get 45 degrees.
135+135=270
360-270=90
90/2=45
