Answer:plz make me brainlist

Step-by-step explanation:

Let the numbers of side of regular polygon be N

Sum of interior angle of regular polygon =(n - 2) * 180.

And according to the question sum of interior angles =4140°

So. The number of sides

=> (n - 2) * 180 =4140°

=>(n - 2) =4140/180

=>n-2=23°

=>n=23+2

Therefore n=25

Number of diagonal =n-2

=25-2

=23
