Question

find the sum of the interior angles of a regular polygon that has 8 sides​

Answer 1

(n-2)180
Where n is the no. of sides
So, 6 x 180 = 1080

Answer 2

Given

A Polygon is 8 Sides

We Find

Sum of Interior Angle

We Know That

Formula for finding solution is :-

$\sf \boxed {\red{ [n - 2]180°}}$

According To The Question

$\implies \sf { [n - 2]180°}$

$\implies \sf { [8 - 2]180°}$

$\implies \sf { 6 × 180°}$

$\implies \sf { 1080°}$

Hence, Sum of the Interior Angle of a Given Polygon is 1080°.
