See this question-
I tried solving this question and I was able to find out the value of BF.I found it this way,
First of all, construct EG parallel CF meeting AB at point G.Then, in triangle BEG, BF=GF.........(i)
Again, in triangle ACF, we have AG=FG...(ii)
So,From (i) & (ii), BF=GF=AG
Also, AF=9.
Thus, 2AG=9
=> AG = 4.5
AG=GF=BF= 4.5
But, if you will check out the options for the length of BF then there is no any option for the value 4.5.
So, do you agree with me that the options for this question are incorrect?
Along, with it also tell me how to find out the value of OD?
