Project Euler > Problem 195 > Inscribed circles of triangles with one angle of 60 degrees (Java Solution)


Let's call an integer sided triangle with exactly one angle of 60 degrees a 60-degree triangle.
Let r be the radius of the inscribed circle of such a 60-degree triangle.

There are 1234 60-degree triangles for which r [≤] 100.
Let T(n) be the number of 60-degree triangles for which r [≤] n, so
T(100) = 1234, T(1000) = 22767, and T(10000) = 359912.

Find T(1053779).



The solution may include methods that will be found here: .

public String run();
