If the number of diagonals of a regular polygon of n sides is 104 , then n =

Options

  1. A19
  2. B16
  3. C13
  4. D11

Correct answer

B. 16

Step-by-step solution

We know that, Number of diagonals of a regular aligned & polygon of n sides = (n-3) n 2 & 104= (n-3) n 2 & n=16 and n=-13 (Rejected) & n=16 aligned
