Question

While vacationing in Egypt, the Greek
mathematician Thales calculated the height of the
Great Pyramid. According to legend, Thales placed
a pole at the tip of the pyramid’s shadow and used
similar triangles to calculate its height. This
involved some estimating since he was unable to
measure the distance from directly beneath the
height of the pyramid to the tip of the shadow.
From the diagram, explain his method. Calculate
the height of the pyramid from the information
given in the diagram.
