Your first step is to add all of the interior angles together, and then subtract it from the total sum of the interior angles of the shape that your working with.
If you don't know what the sum of all of the interior angles are for the shape you are working with, you can easily look it up on google to be sure.
<em>If you have anymore questions, </em>Don't be afraid to ask! I'm always glad to help, also if I am wrong please let me know and I promise I will come back and rework my math.
