∠MHL and ∠MHJ are supplementary angles that is some of the measure of both angle is 180°, because these angle are on a line.
∠MHL + ∠MHJ = 180°
substituting values.
⟹ (2m + 10)° + (5m + 100)° = 180°
⟹ 5m + 2m + 10 + 100 = 180°
⟹ 7m + 110 = 180°
⟹ 7m = 180° - 110°
⟹ 7m = 70°
⟹ m = 70/7
⟹ m = 10
m = 10°
measure of ∠MHL is
⟹ (2m + 10 )°
⟹ 2(10°) + 10°
⟹ 20° + 10°
⟹ 30°
∠MHL = 30°
Answer:
Required coefficient :coefficient of 1st, 2nd, 3rd and 4th term are 1, 3,3,1 respectively.
Explanation:
Formula for binomial expansion is 
We will substitute the values a=a, b=b and n=3 in the formula for binomial expansion we will get
After simplification of the terms we will get
Since, 
Therefore the required coefficient : coefficients of 1st, 2nd, 3rd and 4th term are 1, 3,3,1 respectively.
