Need help with this math problem

The value of b is: 4
Step-by-step explanation:
The given polygon is a convex polygon with three sides. A polygon with three sides is called triangle. The sum of interior angles of a triangle is 180°
So,
[tex]Sum\ of\ Angles = 180\\(b+41)+(101)+(b+30) = 180\\b+41+101+b+30 = 180\\2b+172 = 180\\2b = 180-172\\2b = 8[/tex]
Dividing both sides by 2
[tex]\frac{2b}{2} = \frac{8}{2}\\b = 4[/tex]
Hence,
The value of b is: 4
