Answer:
c. 180(n - 2)
Explanation:
Note that the variable (n) equals to the amount of sides there are. You can use it to find the total amount of degrees the shape has.
for example, a triangle has 3 sides:
180(n - 2)
180(3 - 2)
180(1) = 180
This means that the sum of the triangle's interior angles is = 180°
Another example can be an pentagon, which has 5 sides:
180(n - 2)
180(5 - 2)
180(3) = 540
This means that the sum of the pentagon's interior angles is = 540°
