Question 397515
<font face="Garamond" size="+2">

The measure of an interior angle of a regular n-gon is given by:

*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{180(n\ -\ 2)}{n}]

So, set that expression equal to your interior measure and solve for n.

*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{180(n\ -\ 2)}{n}\ =\ 170]

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
