Hey ive got a vector proof question that i cant get. Sorry i cant provide a diagram but hopefully you can see where i went wrong. 1. The problem statement, all variables and given/known data For triange PQR with with X dividing vector PR in the ratio of 2:3, Y the midpoint of vector PQ and Z the pint of intersection of QX and RY prove that Z divides RY in the ratio 3:1 2. Relevant equations first i said that vector RZ was a scalar multiple of vector RY. RZ=sRY and my second equation was RZ=tRQ + (1-t)RX 3. The attempt at a solution first i got both equations in terms of sides of the triange. RZ=s(RQ+1/2QP), and RZ=tRQ +(1-t)3/5(RP) RZ=tRQ+3/5(1-t)(RQ+QP) then i set the two equations equal to each other and attempted to solve for s and t. I ended up getting s=6/5 and t=2/3. Any help?
