Determine the ratios

  1. Jun 10, 2007 #1
    1. The problem statement, all variables and given/known data
    in the parallelogram ABCD, DC is extended to E so that DE:EC= 3:2. The line AE meets BC at F. Determine the ratios in which F divides BC and F divides AE

    3. The attempt at a solution

    so i figured i could use the division-point theorem

    OP=[b/(a+b)]*OA +[a/(a+b)]OB

    but i don't know how to use this equation in this case..i really don't know how to get started T-T

    I'm not sure I understand, ED < EC so how can the ratio be 3:2?? I am familiar with external division of a point but are you sure that is it?
