Question 1076240: An aerial photograph from a U-2 spy plane is taken of a building suspected of housing nuclear warheads. When the photograph is taken, the angle of elevation of the sun is 41 degrees. By comparing the shadow cast by the building in question to the shadows of other objects of known size in the photograph, scientists determine that the shadow of the building in question is 84 feet long.
How tall is the bulding? (Round your answer to two decimal places.)

Let n be the height of the building. Then we know that n/84=tan 41�. So:
n/84= tan 41�
n/84=0.86928673781622666220009563870394
n=73.02 ft. as the height of the building. ☺☺☺☺
