Question 97249: In the past, the Forestry Service has used fire lookout towers to watch for fires by providing a view of the surrounding countryside. If a post 2 feet tall, near the tower, casts a shadow that is 31/2 feet long and the tower casts a shadow that is 168 feet long. How tall is the tower?

--------------
x/168 = 2/(7/2)
x /168 = 7
x = 1176 ft
