What is the sum of the interior angles of the polygon shown below?

Given:
Polygon
To find:
The sum of the interior angles of the polygon.
Solution:
Number of sides = 7
Sum of the interior angles formula:
[tex]\text{Sum}=(n-2)\times 180^\circ[/tex]
Substitute n = 7 in the formula.
[tex]=(7-2)\times 180^\circ[/tex]
[tex]=5\times 180^\circ[/tex]
[tex]=900^\circ[/tex]
The sum of the interior angles of the polygon is 900°.
