Answer:
m<1 = 80 degrees
m<2 = 57 degrees
m<3 = 57 degrees
m<4 = 43 degrees
m<5 = 137 degrees
m<5 = 123 degrees
Step-by-step explanation:
Angle 1: Vertical angles
Angle 2:
43+80 = 123, 180-123 = 57
Angle 3: Corresponding to m<2
Angle 4: Corresponding to the 43 degree angle
Angle 5: m<1 + m<2 = 137 degrees (Corresponding)
Angle 6: m<3+m<6 = 180 degrees. 180-57=123
