a tree casts a shadow that is 24 ft long. a 4-ft tall young boy casts a shadow that is 3 ft long. the two triangles created are similar. how tall is the tree?
The ratio 4:3 is the boy and its shadow and that equals 3/4. x:24. So, we have to find out x. 24/3 is 8 and you have to multiply 4 and 8 to get 32 feet as the tree's height.
