12. What is the sum of the interior angles for a pentagon?
O 900°
O 540°
O 720°
O 108⁰
O 540°
yep 540
The sum of the interior angles for a polygon can be found using the formula (n - 2) * 180, where n represents the number of sides of the polygon.
For a pentagon (a polygon with 5 sides), the sum of the interior angles would be (5 - 2) * 180 = 3 * 180 = 540°.
So, the correct answer is O 540°.
To find the sum of the interior angles of a polygon, you can use the formula:
Sum of interior angles = (n - 2) * 180°
where "n" is the number of sides of the polygon.
In this case, we have a pentagon, which has 5 sides. Plug in the value of "n" into the formula:
Sum of interior angles = (5 - 2) * 180°
= (3) * 180°
= 540°
Therefore, the sum of the interior angles for a pentagon is 540°.
So, the correct answer is O 540°.
