Hey, I've been struggling with for a while today and my teacher did a horrible job at explaining. I need help finding the values of M1 and M2.

Answer:
43°
Step-by-step explanation:
angle 1 and Angle 2 are corresponding angles. app they are equal.
73-2x = 88-3x
x = 15
angle 1 = 73-(2*15) = 43
angle 2 = 88-(3*15) = 43
