Question

a polygon has 16 faces find how many diagonals are present in the polygon?

Answer 1

Hii..
Here is your answer..

Solution:-
Number of faces is 16.

Now , we 'll use one formula to calculate the number of diagonals in the polygon:-

$= > d = \frac{(n)(n - 3)}{2}$
Here,
n is equal number of faces
d is equal to diagonal

So,
$= > d = \frac{(16)(16 - 3)}{2}$
$= > d = \frac{16 \times 13}{2} \\ = > d = \frac{208}{2} \\ = > d = 104$
Hence,
Number of diagonal is 104.

Hope it helps uh...
