Answer:

b=59

Explanation:

angles in the triangle add up to 180

this would mean that

38 +2b-20 + b-15 = 180

if we simplify this then it would be

3+3b= 180

rearrange

3b = 177

b = 59

Answer:

59

Explanation:

We know that all the angles must add up to 180

so we have

38+2b-20+b-15=180

solve for b

3b+3=180

3b=177

b=59
