To find the exterior angle of a polygon, you can use the formula for the sum of the exterior angles of any polygon, which is always 360 degrees, regardless of the number of sides.
For a regular polygon (where all sides and angles are equal), the measure of each exterior angle can be calculated by dividing 360 degrees by the number of sides (n):
\[ \text{Exterior angle} = \frac{360°}{n} \]
In your case, for an 11-sided polygon (n = 11):
\[ \text{Exterior angle} = \frac{360°}{11} \approx 32.73° \]
So, the approximate degree measure of the exterior angle of the 11-sided polygon would be about 32.7°.
Thus, the correct response would be 32.7°.
