    The angle made by the hands is 120 degrees. How about the law of cosines to find the missing side of the triangle?

    Since there are 12 hours on the clock face, divide 360 by 12.

    When the hand moves from the 12 to the 1, it goes 30 degrees. So when it goes from the 12 to the 4 it goes 4 times 30 or 120 degrees.
