Question
- If a regular polygon is having 12 sides, then find the interior and exterior angles. a) 120 oand 60 ob) 30 oand 150 o c) 145 oand 35 od) 150 oand 30 o
Solution
The formula for calculating the interior angle of a regular polygon is (n-2) * 180 / n, where n is the number of sides.
So, for a 12-sided polygon, the interior angle would be (12-2) * 180 / 12 = 150 degrees.
The exterior angle of a regular polygon is calculated as 360 / n.
So, for a 12-sided polygon, the exterior angle would be 360 / 12 = 30 degrees.
Therefore, the correct answer is d) 150 o and 30 o.
