$\frac{BC}{PR} = \frac{BQ}{PQ}$

I think the second one is too small

ganeshie8 · Answer

you're good at guessing, and its correct that its not the second one :)

anonymous · Answer

It was more of an elimination

ganeshie8 · Answer

ganeshie8 · Answer

i would have gone wid my donkey method.. lol i dont see yet hw to eliminate

anonymous · Answer

It appear to be the correct one... The first one's out.. the third one is discounted... I was down to the last two... the second seemed too small.. so only the last one's left.
