Question

Which formula can be used to find the sum of the measures of all the interior angles of a regular polygon with n sides?

A. S = (n + 2)90
B .S = (n + 2)180
C. S = (n - 2)180
D. S = (n - 2)90

Answer 1

Answer: s=(n-2)*180

Step-by-step explanation: you don't add 'n' and 2 you have to subtract.

For example: a hexagon is (6-2)*180=720

Answer 2

b. S=(n+2)180                                                                                                            i hope it help
