To find angle \( b \) using the properties of exterior angles of triangles, remember that the measure of an exterior angle is equal to the sum of the measures of the two opposite interior angles.
If you have an exterior angle formed by extending one side of a triangle, you can use the relationship:
\[ \text{Exterior Angle} = \text{Interior Angle 1} + \text{Interior Angle 2} \]
If you can specify the values of the interior angles, we can use that to solve for angle \( b \). Based on the available response options (92°, 232°, 38°, 52°), see if you can determine the exterior angle or relate it to the given angles.
Please provide more details about the diagram or the angles involved, and I can assist you better.
