[(n-2)x180]/n=interior angle measure of any regular polygon

Above is the formula for finding the number of sides to a regular polygon. Because what you describe is not a regular polygon, an** irregular**, it is** impossible **to decipher what the amount of sides, therefore you have given everybody a **trick question** to answer. This leaves all answers before this null and void with inaccurate result. Also waltjhall has the wrong formula and obviously does not realize that you can never have a decimal in the number that n is equal to.
