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

Explanation:
<span>Geosphere <span>is considered as one of the portions of the Earth's system which
covers the Earth’s interior, minerals and rocks, the different landforms and
the processes that forms the surface of the Earth. It is the external part of
the Earth that constitutes the crust and upper mantle. The geosphere or lithosphere is about 35 mi (55km) thick
beneath the ocean and up to approximately 124 mi (200 km) thick beneath the
continents. </span></span>
