The number of diagonals that can be drawn in a pentadecagon are to be calculated

Expert Solution & Answer

Answer to Problem 15RP

The number of diagonals is d=90

Explanation of Solution

Given information : A pentadecagon is fifteen-sided polygon.

Formula used:The number of the diagonal is given by the following formula

d=n(n−3)2

Where

“ n ” is the number of the sidesCalculation : We know that for a n sided polygon, the number of diagonals that can be drawn on it are calculated as

d=n(n−3)2

Now, we put the value of n as fifteen in the given formula, thus we get

d=90
