Problema Solution

On a sunny day, a tree and its shadow form the sides of a right triangle. If the hypotenuse is 52m long and the tree is 48m tall, how long is the shadow?

Answer provided by our tutors

By pythagoras' theorem

shadow^2 + tree^2 = hyp^2

so, shadow = root(hyp^2 - Tree^2)

= root(52^2 - 48^2) = root(400)

= 20.... answer
