Answer 1

Solution :

The sum of the interior angles of a polygon is four times the sum of its exterior angles.

The sum of the exterior angles of a polygon is always equal to 360°

The sum of the interior angles of polygon = 180 (n − 2)

$\implies \: 180(n - 2) = 4 \times 360 \\ \implies \: n \: - 2 = 8 \\ \implies \: n \: = \: 10$

Number of sides in the polygon = 10
