How many sides has a polygon if the sum of its interior angle is 1440o?
Answer Details
To find the number of sides of a polygon given the sum of its interior angles, we can use the formula:
Sum of interior angles = (n - 2) × 180°
where "n" is the number of sides of the polygon.
We are given that the sum of the interior angles of the polygon is 1440°. Substituting this value into the formula, we get:
1440° = (n - 2) × 180°
Simplifying this equation, we can divide both sides by 180:
8 = n - 2
Adding 2 to both sides, we get:
n = 10
Therefore, the polygon has 10 sides.
