How many triangles are there in a polygon, if the polygon has 44 diagonals?
Please check the wording of the problem . . .
A convex polygon with sides has: . diagonals.How many triangles are there in a polygon, if the polygon has 44 diagonals?
. . But . .has no integral solutions. . . . . . wrong!
I did some very bad algebra . . . sorry!
There is any polygon of concave? My friend ask this question to me, So i can not check the question again, i asked him about the question he said it is the correct one.
n=-8 or n=11
Since n denotes side, it can not be negative. So, n=11.
So, it is a polygon of 11 sides.
Can you please help me in finding out the number of triangles in the 11 sided polygon?
