Ângulos: The figure shown consists of a shaded regular 11-sided polygon and 11 unshaded isosceles triangles surrounding it. For each isosceles triangle, the longest side is a side of the shaded polygon, and the two equal sides are formed by extending the two adjacent sides of the polygon. At each vertex, the two extended sides form a vertex angle labeled b°, as shown in the diagram. What is the value of b?
