how many sides does a regular polygon have if the measure of an interior angle is 160 degrees? justify ur answer EXPLAIN HOW PLSSS

Step-by-step explanation:

Size of Interior angle = 180° - 360°/n, where n is the number of sides of the regular polygon.

We have 180° - 360°/n = 160°.

=> 360°/n = 20°, n = 18.

Therefore it is a 18-sided regular polygon.
