Final answer:

To determine the number of sides of a regular polygon where each interior angle is 162°, we use the formula for the measure of an interior angle of a regular polygon. Solving for n we find that the polygon must have 20 sides, which doesn't match any of the options given, indicating a potential error in the question or options.

Step-by-step explanation:

The question is asking to determine the number of sides of a regular polygon given that each interior angle measures 162°. To solve this, we use the formula for the measure of each interior angle in a regular polygon, which is:

(n - 2) × 180° / n

Where n is the number of sides. We can set up the equation as follows:

162° = (n - 2) × 180° / n

Solving for n we get:

n - 2 = 162°n / 180°

0.9n - 2 = 162°n / 180°

162n = 180n - 360

18n = 360

n = 20

Since n must be an integer, we can see that the number of sides is 20, which is not listed among the provided options, indicating a possible error in the question or the options given.
