Question

Find the measure of each interior angle of a regular 18-gon?

Answer 1

Answer: $160^{0}$

Step-by-step explanation:

The first thing is to find the sum of angles in a 18-gon using the formula:

$(n-2)180$

That is

$(18-2)180$

= 16 x 180

= $2880^{0}$

Since it is a regular 18-gon , this means that each interior angles are equal , so the measure of each interior angle will be :

2880/18

= $160^{0}$
