#### PrepInsta User

No. of diagonals given = 77 no. of sides of the polygon can be determined by the formula, diagonal = n*(n-3)/2 from the given data we have, 77 = n*(n-3)/2 77*2 = n*(n-3) 154 = n^2 - 3n 0 = n^2 - 3n - 154 0 = n^2 -14n + 11n - 154 0 = n(n-14) +11(n-14) 0 = (n+11) and (n-14) here, n+11, n = -11 (not possible) where as n-14, n = 14 (answer)

#### PrepInsta User

(N(N-3))/2=Y where Y = no. of diagonals and N = no. of sides so, (14*11)/2=154/2=77.

#### PrepInsta User

d=s(s-3)/2 where d= no of diagonals s=no of sides
