The sum of the angles of a triangle is 180 degrees. If one angle measures x degrees, a second angle measures 3x degrees, and a third angle measures 7x degrees, express the measure of the fourth angle in terms of x.

  3. x + 3x + 7x = 180
    11x = 180
    x = 16.3636

    7 * 16.3636 = about 114.545 degrees
