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

We know that sum of interior angles of a $n$ sided polygon is given by $\left(n - 2\right) \cdot 180$ degree.
Where $n$ is the number of sides.
Here sum of interior angels is $2340$ degrees.
$\implies \left(n - 2\right) \cdot 180 = 2340$
$\implies n - 2 = 13$
$\implies n = 15$
$\implies$ number of sides$= 15$
