Observe the figures:

\

Consider the first triangle is \"\" and second triangle is \"\".

\

If \"\" and \"\" are similar, then measures of their corresponding sides are proportional.

\

Here, \"\" and \"\".

\

\"\"           (Corresponding sides are proportional) \ \

\

\"\"                      (First proportion)

\

\"\"                          (Substitute \"\" and \"\")

\

\"\"                        (Find the cross product)

\

\"\"                           (Multiply)

\

\"\"                      (Divide each side by \"\")

\

\"\"                              (Cancel common terms)

\

Therefore,  the side of the triangle \"\" is \"\".

\

Option F is right choice.
