Answer:
5 sides
Explanation:
A polygon includes the shape pentagon which has 5 sides.
If n are number of sides of a convex polygon, sum of its interior angles is 540 degrees.
As in given case sum of interior angles is 540°, we have
( n − 2 ) × 180 ° = 540°
When we solve this equation, we get 5 sides.
We can check this by plugging 5 into n, so the equation is
(5 - 2) x 180° = 540, this becomes...
3 x 180 = 540; this is correct so you answer is 5 sides.
