We will follow this strategy: we will find the value of x using a theorem about the sum of interior angles of any polygon, and then we will compute 2x to find A.
The theorem states that the sum of the interior angles of <em>any</em> polygon with sides is
Your polygon has seven sides (so ), and the sum of the interior angles is
So, using the theorem, we know that
.
Since and , we have
