Question

Find the sum of interior angles of a polygon of given number of sides by using
formula (n - 2) × 180°
12 sides​

Answer 1

Answer:

The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides. The problem concerns a polygon with twelve sides, so we will let n = 12. The sum of the interior angles in this polygon would be 180(12 – 2) = 180(10) = 1800.

Answer 2

Step-by-step explanation:

$= (n - 2) × 180°(n = 12) \\ = (12 - 2) \times 180 \\ = 10 \times 180 \\ = 1800°$
