Which expression gives the sum of the interior angles of a simple polygon with n sides?
A) (n - 1)90°
B) (n - 2)180°
C) 2(n - 2)60°
D) 2(n + 2)30°

B

Step-by-step explanation:

C and D are not simplified to lowest terms, and recalling that the sum of the interior angles of a square is 360, A does not work.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
