The formula for getting the number of diagonals of a certain polygon is:
N (N-3) / 2
where n stands for the polygon..
But here's the question:
What kind of polygon has 54 diagonals?
I tried to manipulate the formula as in reciprocated it in this form:
54 divided by the difference of 54 and 3 then multiply the quotient by two
The answer I obtained is 2.11
Please help me...Please teach me how to manipulate a formula..I also tried to use the triangle method but it doesn't work...
