Question

A regular polygon has 20 sides. The measure of an exterior angle of this polygon is ​

Answer 1

Answer:

Sum of interior angles is 180° (n - 2). The way I remember this equation is by remembering that the equation contains 180° and the number of sides, and that the sum of interior angles of a triangle is 180°.

180° (18 - 2)

180° (16)

(200 - 20)° (16)

(3200 - 320)°

2880°

Step-by-step explanation:

Answer 2

Answer:

18 degrees

Step-by-step explanation:

Sum of all exterior angles of a  regular polygon = 360

So the measure of one exterior angles = 360/20 =18
