9-150.

How tall is the tree?

Since the shadow lengths are proportional to their heights, we can create an equation using the given ratios.

Relate the shadow length to height ratios for the tree and for Jack and then solve for the unknown variable of the tree's height.

Tree's height =

ft. Will the tree hit the fence if the fence is

feet away? Based on the answer from part (a), was the tree's height taller than nine feet?
