Let its sides be x and use the formula: 0.5*(x squared-3x) = 230
So: x squared-3x-460 = 0
Solving the quadratic equation gives x positive value of 23
Therefore the polygon has 23 sides irrespective of it being a regular or an irregular polygon.
Check: 0.5*(23^2-(3*23)) = 230 diagonals
It has 9 sides and it can be an regular or a irregular polygon which is called a nonagon Check: 0.5*(81-27) = 27 diagonals
Let the number of sides be x and by solving the equation for diagonals 0.5(x*x-3x) = 135 the solution is -15 or 18 and so therefore it has 18 sides irrespective if it is an irregular or a regular polygon
A polygon that has 104 diagonals will have 16 sides
how many diagonals are there iin a polygon of 11 sides
That polygon is called a "triangle". It has no diagonals.
A regular octogon (8 sides) has 20 diagonals. An irregular octogon also has 20 diagonals, but only if all its points point outwards.
A 7 sided polygon has 14 diagonals
38 diagonals
There are 77 diagonals
An heptagon has 7 sides and 14 diagonals
The five sided Polygon has 5 diagonals
Let its sides be x and rearrange the diagonal formula into a quadratic equation:- So: 0.5(x^2-3x) = 252 Then: x^2-3n-504 = 0 Solving the quadratic equation: gives x a positive value of 24 Therefore the polygon has 24 sides irrespective of it being irregular or regular
