To determine the number of degrees in a pentagon, we need to understand its interior angles.
A pentagon is a polygon with five sides. To find the total degrees of its interior angles, we can use the formula:
Total degrees = (n - 2) × 180
In this formula, "n" represents the number of sides of the polygon. For a pentagon, "n" is equal to 5.
Let's substitute the value of "n" into the formula:
Total degrees = (5 - 2) × 180
Total degrees = 3 × 180
Total degrees = 540
Therefore, a pentagon has a total of 540 degrees.
