Question

The sum of the interior angles of a polygon is 14 × 180 . Work out the number of sides of the polygon.

Answer 1

Number of sides of the polygon = 16

Explanation:

Sum of the interior angle of a polygon = (n - 2) × 180°

Here, n = Number of sides of the polygon

If sum of the interior angles = 14 × 180°

Therefore, (n - 2) × 180° = 14 × 180°

(n - 2) = 14

n = 14 + 2

n = 16

Number of sides of the polygon = 16
