Answer:
m<1 = 75
m<2 = 55
m<3 = 55
Explanation:
Well <1 + 50° is vertical to 125 so do this
<1 + 50 = 125 (subtract 50 on both sides)
<1 = 75
Now <1 + <2 + 50° = 180
We know what <1 is so..
75 + <2 + 50 = 180 (collect like terms)
125 + <2 = 180 (subtract 125 on both sides)
<2 = 55
Since <2 and <3 are vertical that means they equal the same so
<3 = 55
