Question

Tall hedges are shading a rose garden. At the time the gardener wants the garden to be in sunlight, a four- foot vertical pole casts a five foot shadow. Suppose that we want to cut the hedges back only to a height of 8 feet. How far must the edge of the garden be from the base of the hedge if we do not want any part of the rose garden to be in the shade?

Answer 1

Explanation:

A 4-ft pole casts a 5-ft shadow, so an 8-ft hedge casts a 10-ft shadow. Tge hedges must be 10 ft from the garden.
