Question

The sum of a polygon’s interior angle measures is 2340 degrees. What kind of polygon is it?

Answer 1

We know that sum of interior angles of a `n` sided polygon is given by `(n-2)*180` degree.
Where `n` is the number of sides.

Here sum of interior angels is `2340` degrees.
`implies (n-2)*180=2340`
`implies n-2=13`
`implies n=15`
`implies` number of sides`=15`
Therefore, the polygon is 15 sided.
