A 6-foot-tall climber casts a 20-foot-long shadow at the same time that a tree casts a 90-foot-long shadow. how tall is the tree?

Question

anonymous · Answer

the answer is 27 ft.The key to solving the problem about how tall a tree that casts a 90 foot shadow when the 6 foot person casts a 20 foot shadow is finding the proportion. If you set up the equation 90/20 = x/6 and cross multiply, then solve for x, the answer is that the tree is 27 feet.|dw:1427414544667:dw|
