    That was a thought question.

    What is the length of AB and how did you determine it?

    AB is the median of trapezoid QRST.

    The length of the median of a trapezoid is one-half the sum of the lengths of the two bases.

    AB=\frac{RS+QT}{2}

    Substitute known values for RS and QT and solve for AB.

    Since JK is a median of trapezoid ABTQ,

    JK=\frac{AB+QT}{2}

    All variables except JK should be known at this point, so substitute values for AB and QT and find JK.
