Answer:
Step-by-step explanation:
The sum of the interior angles of a polygon with 
sides is 
. Since the shape in the figure has 5 sides, the sum of its interior angles is 
.
Therefore, we can set up the following equation:
Since 
and 
make up one side of a line, they are supplementary, as each side of a line is 
.
Thus, we have:
