Answer:
m<1 = 70 m<2 = 110 m<3 = 70 m<4 = 110
Step-by-step explanation:
m<2 and m<4 equal the same amount, so since when they are added they equal 220, you can just divide by 2.
220/2 = 110
so, m<2 and m<4 both equal 110.
A straight line has an angle of 180, so you can take 110 from angle m<2 and subtract it from 180 to find m<1
180 - 110 = 70
m<1 = 70
m<1 and m<3 also both equal the same amount, so they both equal 70.
m<1 = 70 m<3 = 70
