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 
Answer:
