To find the sum of the interior angles of a polygon, you can use the formula:
\[ S = (n - 2) \times 180^\circ \]
where \( S \) is the sum of the interior angles and \( n \) is the number of sides of the polygon.
If you know the number of sides of the polygon (let's denote it as \( n \)), you can substitute that value into the formula to get the sum of the interior angles.
For example, if the polygon is a quadrilateral (4 sides), the calculation would be:
\[ S = (4 - 2) \times 180^\circ = 2 \times 180^\circ = 360^\circ \]
If the polygon is a hexagon (6 sides):
\[ S = (6 - 2) \times 180^\circ = 4 \times 180^\circ = 720^\circ \]
Just replace \( n \) with the number of sides in your polygon to calculate the sum of the interior angles. If you provide the number of sides, I can calculate it for you.
