Question 971270: I have figured out the following:
What size is the interior angle of a regular 15-sided polygon?
n-2 (180)
15-2 (180)
13 (180)
13(180)
2340 degrees
Now, if one side has a length of 5 feet what is the perimeter?
Can you help?
Thanks,
George

Since all the angles are equal, each direction-change is , and that means that each interior angle is � minus this amount, or

for we will have:
�
then, the sum of all internal angles is:

--------------
if one side has a length of ,and we have sides, then the perimeter is
