The measure of each exterior angle

`
Question:

The measure of each exterior angle of a regular polygon of 18 sides is __________.

Solution:

The measure of each exterior angle of a regular polygon of 18 sides is 20o.

We know that, the measure of each exterior angle of a regular polygon is 360o/n.

Where ā€˜nā€™ is the number of sides in the polygon,

Then, polygon has 18 sides, i.e. n = 18

So, 360o/18

= 20o
