i don't understand this stuff! the videos don't help. does anyone know this answer

Answer:
540°
Step-by-step explanation:
The sum of the interior angles of a polygon is found using the following formula:
Sum of Interior angles = (n - 2) x 180
Note that: n = the # of sides.
There are 5 sides, making n = 5. Plug in 5 for n in the equation:
(n - 2) x 180 = (5 - 2) x 180
Simplify. Remember to follow PEMDAS. First, solve the parenthesis, then multiply:
(5 - 2) = 3
3 x 180 = 540
540° is your answer.
