Answer:
41
Explanation:
Theorem:
The measure of any exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.
The angle measuring b + 41 is an exterior angle.
The angles measuring b - 2 and b + 2 are the remote interior angles to the exterior angle.
According to the theorem:
b - 2 + b + 2 = b + 41
2b = b + 41
b = 41
