    need help with a question
    #Q4. its at the top of the page at


    I honestly am just totally stumped, i dont know where to start, i have looked through all my notes and i cant find a thing to help me.

    the only think i can gather is
    Pb = 15Pd
    but i dont know how to work out Tb
    (that is if Pb is the vertex, if it is where is the other one?)

    If its possible to help me thank you very much
