    50 = \frac{100}{2}(t-sin(t))

    cannot be solved using algebra, you will have to employ a numerical method.

    You can make

    50 = \frac{100}{2}(t-sin(t))

    into

    50 = 50\times(t-sin(t))

    1 = (t-sin(t))

    t = sin(t)

    Then either graph them to find an approximate value or even pop the equations into a spreadsheet, that should get you close.
