Find the nu

Answer :


a polygon of 16 sides

We have given that polygon has 16 vertices and each side and diagonal can be formed by joining two vertices of a polygon,


Let us assume the no. of diagonals of the polygon are N,


N = (no. of lines formed on joining any two vertices) – (no. of sides of the polygon)


N = 16C2 – 16


We know that ,


And also n! = (n)(n – 1)......2.1





N = 120 – 16


N = 104


The total no. of diagonals formed are 104.
