Answer:

42•5°

Explanation:

We know, sum of the angles of triangles is 180°

m° + 2m° + (m + 10)° = 180°

or 3m° + m° + 10° = 180°

or 4m° - 10° + 10° = 180° - 10°

or 4m° = 170°

or 4m° / 4 = 170° / 4

or m° = 42.5°

Therefore, m = 42.5°

Explanation:

180°=m+2m+(m+10)

180°=4m+10

4m=180-10

m=170÷4

m=42.5

2m=42.5x2=85°

(m+10)=42.5+10=52.5°
