    This is not a simple problem, for starters the form that the zip line hangs in is a catenary. Also these problems do not usually have closed from solutions and have to be solved numerically.

    There is a related post on MHF here, which in itself will not be of much help but there is a link in that post that will.

    The problem has actually been simplified so that the zipline is a straight edge between each given point. You don't have to worry about the curvature.

    How do you know this?
    If that is the case then how could it have different angles at each end?
