(n-2)*180 degree...

Question

The sum of the interior angles of a polygon can be found using: 

(n-2)*180 degree

Where n= the number of sides in the polygon

What is the interior angle sum of an eight-sided shape?

 

Answer 1

Hi!  In the formula you have written, "n" is equal to the number of sides of the polygon.  If you are looking for the interior angle sum for an 8-sided figure, what should you plug in for n?  You can then use the formula and find the interior angle sum.

Answer 2

This is a duplicated submission. I direct you to the other submission, where I give an answer but also point out the deficiency in the wording of this problem.

Answer 3

You have been given a reliable formula. And you've been given n=8.

 

Your job is to calculate the total # of degrees in the sum of all interior angles.

 

Next, you can calculate the NUMBER OF DEGREES IN ONE OF THE 8 ANGLES, PROVIDED YOU ASSUME THAT THE STATED OCTAGON IS REGULAR, by dividing the aforementioned total by eight.

 

But the problem is flawed by not mentioning the regularity of the octagon.
