The sum of the interior angles in the polygon whose side is 10 is 
<h3>What is sum of interior angle of polygon ?</h3>
The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon.
As, The formula for calculating the sum of interior angles is ( n − 2 ) ×
S0, n=10
Then, sum of interior angle be = (n-2) x 180
= (10-2) x 180
= 8 x 180

Thus, the sum of the interior angles in the polygon is
