Step-by-step explanation:
Let the number be
.
Then,

This implies that;

We multiply both sides by
to obtain;



Or

Answer:
Sum of the interior angles = (n-2) x 180°
where
n is the number of sides of the polygon
Step-by-step explanation:
The formula for the sum of the interior angles of a polygon is:

where
is the sum of the interior angle of the polygon
is the number of polygons
Let's check the formula using an example:
We want to find the sum of the interior angles of a square, we know that a square has 4 sides, so
.
Replacing values



We can apply the same procedure to any convex polygon with n sides.
