Answer: 110
Explanation:
so what I did is I took the degrees it gave you, and found that 13= 40 bc 80+60=140, 180-140=40. Which means 10 is 40. So because a triangle has to equal 180 degrees, 180-40= 140, 140/2= 70 so 6 and 7 are 70 degrees. Which means 4 is also 70. 3 and 4 make a straight line so 180-70= 110.
So m<3 is 110
