Question

The sum of all the interior angles of a regular polygon is twice the sum of its exterior angles. Find
the number of sides of the polygon.​

Answer 1

Step-by-step explanation:

$\implies$ $180(n-2)\:=\:2(360)$

$\implies$ $180n-360\:=\:720$

$\implies$ $180n\:=720+360$

$\implies$ $n\:=\Large\frac{1080}{180}$

$\implies$ $\large\boxed{n=60\:sides}$
