How many triangles are there with integer sides and perimeter 2007? How many of these are equilateral? How many are isosceles? How many are scalene
Re: How many
Let the triangle have sides a,b,c, with a≥b≥c. We want to solve the equation a+b+c=2007 in positive integers.
the 167/2 is the -1/2 i pulled out from all the even numbers in the summation, altough im a bit tired so I may have calculated wrong somewhere
