    32 degrees

    Step-by-step explanation:

    The interior and exterior of X must equal 180 degrees.

    X + W = 180

    Plug in 100 for W and subtract it from both sides.

    180 - 100 = X = 80 degrees.

    The total of the internal angles of a triangle are 180 degrees.

    80 + 68 + Y = 180

    Solve for Y: Y = 180 - 68 - 80 = 32 degrees.
