how many diagonals does a polygon with 23 sides have , if one of its vertices does not connect to any diagonal ?
"if i calculate it using the formulae , # diagonals = n ( n - 3 ) / 2 each vertex sends of n - 3 diagonals n = 23 - 1 then 22 * ( 22 - 3 ) / 2 = 209 correct option : e"
divide(multiply(subtract(23, const_1), subtract(subtract(23, const_1), const_3)), const_2)
