From the , the lines and are parallel, .

By Triangle Proportionality Theorem, in a triangle if a line is parallel to one side of the

triangle and intersects the other two sides in two distinct points, then it separates these

sides into segments of proportional lengths.

Since , .

Find LT.

                       (Apply Segment addition postulate)

                            (Substitute )

                                  (Subtract 3 from each side)

Use the proportion to determine WS.

                        (Write the proportion)

                           (Substitute )

                    (Apply cross products property)

                            (Multiply: )

                               (Divide each side by 3)

The measure of WS is 10.
