There are 18 sides
The measure of one exterior angle of a regular 18-gon is 20°. The sum of all exterior angles of a regular polygon is always 360° so the measure of each exterior angle can be calculated by dividing 360° by the number of sides. In this case that would be: 360° 18 = 20°Therefore the measure of one exterior angle of a regular 18-gon is 20°.
It has 18 sides and interior angles,which of them are 160 degrees each and 2880 degrees total and is also called an octadecagon or octakaidecagon.
360/18 = 20 sides
If you say this shape is 18 sided i would guess it has 18 sides. ;)

Interior angles of a regular 18 gon (octdecagon) are 160o.

18-2 * 180 = 2880degrees(number of sides - 2) * 180 will work for any "gon
160 degrees one angle of a regular n-gon= ((n-2)*180)/n ((18-2)*180)/18 (16*180)/18 2880/18 160
The question makes no sense since a 18-gon cannot be added. You can add the measures of its interior or exterior angles, or the lengths of its sides, its diagonals and so on. But there is no such thing as a "sum of 18-gon".
Oh honey, an 18-gon is a polygon with 18 sides. It's like a fancy shape that's got more angles than you can count on one hand. So, if you're into geometry and all that jazz, an 18-gon is your new best friend.

If the exterior angle is 18 degrees then it will have 20 sides.
