The distance between a 16-foot flagpole and a 40-foot tree is equal to the sum of the lengths of their shadows. If the flagpole casts a 18-foot shadow, find the distance from the flagpole to the tree

Answer 1

18/16 = 9/8 = x/40

9=x/5

x=45 foot shadow for the tree

45+18 = 63 feet distance from flagpole to tree
