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
