How many diagonals does a polygon with 17 sides have, if one of its vertices does not connect to any diagonal?	Choose the correct option.
A) 102
B) 104
C) 110
D) 90
E) 84

Rationale: "if i calculate it using the formulae , # diagonals = n ( n - 3 ) / 2 each vertex sends of n - 3 diagonals n = 17 - 1 then 16 * ( 16 - 3 ) / 2 = 104 correct option : b"
Answer: B
