yes this problem is truly hard, but i just don't understand why is it considered as one of the hardest problems? i mean, it's pretty obvious that you should use sine rule to catch some relationship between sides and circumradius and deriving the first inequality isn't really hard and after that its easy.The only hard part here is the first step to drop perpendiculars, and after that its kinda easy(well easy compared to many other hard problems, because many other ones include multiple hard steps)
