Question

A 6-ft. vertical post casts a 14-in shadow at the same time a nearby call phone tower casts a 119- ft shadow. how tall is the cell phone tower?

Answer 1

Know about similar triangles?

Answer 2

Start with a simple diagram of the post, tower, and their shadows. View this as if it were a pair of right triangles... since very few buildings are the Leaning Tower of Pizza and you can safely assume a right angle base. Now, the suns rays are the hypotenuse, they cast the shadow using effectively the same angles! That makes a pair of similar right triangles that you can solve using rules of similar triangles such as the ratio of the sides.
