Yes!In the first place, are problems like this even needed to fight the enemy, hmmm?...please prove it more mathematically.You're quick off the mark, Asashio-san!
Go ahead.Using any method that you can think of,If you don't know the answer, then please don't raise your hand from the start.please prove how it is that AF=BF=CF in this situation.I believe the fact that this question is a problem to be solved indicates that, paradoxically, it must be true and can be solved.
Thus, it can be proven that AF=BF=CF.
