A floodlight at ground level 6 feet from a bush 4 feet tall cast a shadow of the bush on a building tha is 24 feet from the bush. What is the height of the shadow
----------------------------------------
Draw the picture. Notice you have two overlapping right triangles.
These triangles are similar.
Proportion:
height of shadow/height of bush = long base/short base
--------------------------------
h/4 = 30/6
h = 20 ft high
