extend the lines of the sides of your polygon out, you should find that each side is a straight line. a straight line = 180 degrees. if you are finding the angle measure of the interior angle, then its 180- 18
answer is 162 degrees.
x degrees ........./18 degrees
-----x degrees/18 degrees----
<<<<>>>
180-18=162
answer 162 degrees:
