What is the sum of the interior angles of a regular polygon with 5 sides?
a 1,080°
b 900°
c 720°
d 540°
The sum of the interior angles of any polygon can be found using the formula:
Sum = (n - 2) * 180°
where n is the number of sides of the polygon.
In this case, n is 5, so the sum of the interior angles is:
Sum = (5 - 2) * 180° = 3 * 180° = 540°
Therefore, the correct answer is option d) 540°.
