Answer:
See below.
Explanation:
I'll explain the method.
I'll do the first 2 lines and last line, and you can do the rest.
The name n-gon means a polygon with n sides, so a 4-gon is a 4-sided polygon (called a quadrilateral). A 12-gon is a polygon with 12 sides. A 47-gon is a polygon with 47 sides.
The number of angles is the same as the number of sides, so a 47-gon has 47 sides and 47 angles.
The measure of each interior angle for a regular n-gon is
[180(n - 2)]/n
Subtract 2 from the number of sides. Multiply that number by 180. Divide by the number of sides.
The measure of each exterior angle for a regular polygon is 360 divided by the number of sides.
