a,b,c must have some discreteness limitation, as there are continuously many triangles with such properties for any given n. One can try to guess what designers had in mind. Integers, maybe?Let a, b and c be the sides of a triangle with one angle of 120 degrees, a≤b≤c and b-a≤100. Let T(n) be the number of such triangles with c≤n.

Re: Problem 582
Gosh, you are good at guessing:
Let a, b and c be the sides of an integer sided triangle with one angle of 120 degrees, a≤b≤c and b-a≤100.
