The sum of the interior angles of the polygon shown is 900°.

Solution:

Number of sides of the polygon (n) = 7

Sum of interior angles of a polygon formula:

$\text {Sum}=(n-2) * 180^(\circ)$

Substitute n = 7 in the formula.

$=(7-2) * 180^(\circ)$

$=5 * 180^(\circ)$

$=900^(\circ)$

The sum of the interior angles of the polygon shown is 900°.
