Question

1. what is the sum of the exterior angles, one at each vertex, of a polygon with 20 sides?$\bigcirc$ $180^circLXB0\bigcirc$ we need more information.$\bigcirc$ $360^circ$

Explanation:

Step1: Recall polygon exterior angle rule

The sum of exterior angles (one per vertex) of any convex polygon (regardless of the number of sides) is a constant value.

Step2: Identify the constant sum

This constant sum is $360^\circ$, which applies to all polygons, including 20-sided ones.

Answer:

360°
