2009-09-01 · A boy whose eye level is 1.5 meters above the ground wants to find the height of a tree ED. He places a plane mirror horizontally on the ground 15 meters from the tree. If he stands at a point B which is 2 meters from the mirror C, he can see the reflection of the top of the tree. Find the height of the tree. Hint: the angle of incidence equals the angle of reflection. See figure 2 below.

As an example, most U.S. cooks know what a 1/4 pound of butter looks like - it is a stick about 1 inch x 1 inch x 5 inches. But ask them what 100 g of butter looks like and they may throw up their hands in defeat. The answer is that the ‘metric’ stick is almost the same size as the U.S. stick since 100 g is close to 1/4 pound. Sometimes the units get left off solutions to real problems ...
