    Hello, yvonnex3!

    I assume you made a sketch . . .


    The Vietnam Veterans Memorial in Washington, D.C., is made up of two walls,
    each 246.75 feet long, that meet at an angle of 125.2.
    If extended, the west wall would reach the Lincoln Memorial 900 ft away,
    and the east of the wall would reach the Washington Monument 3500 ft away.
    Find the distance between the Lincoln Memorial and the Washington Monument.
    (nearest foot)
    Code:
                   V  246.75 B       3500         W
                    o--------o--------------------o
           246.75  / 125.2
                  /                       *
               A o
                /                 *
               /
          900 /           *  d
             /
            /     *
           /
        L o

    We have \Delta LVW with: VL = 1146.75,\:VW = 3746.75,\:\angle V = 125.2^o

    And we want: . d = LW

    . . Use the Law of Cosines . . .
