If the size of one interior angle of a regular polygon is 108° how many sides does the polygon have?

Now, recall that the sum of all interior angles is 180(n-2), now, let's say one angle is θ, and there are "n" sides in the polygon, so if add up all the θ angles, what the sum will then be is just θn, or that product, therefore,



and surely you know how much that is.

than do 23.50 times 18 and then divide your answer by 100 than you will get x.

Ithink the answer is b.
