Question

what is the sum of all interior angles of a polygon if x sides​

Answer 1

Answer:

To extend that further, if the polygon has x sides, the sum, S, of the degree measures of these x interior sides is given by the formula S = (x - 2)(180).

Answer 2

Answer:

Sides= x

Sum of all interior angles= 180(no. of sides -2)

                                         = 180(x-2)

To further simplify:

180(x-2)

= 180x - 360 (Because of distributive property)

Thats as much as you can simplify since no other value is given. You can use this as reference for future questions.
