Im suppose to find how high a building is [ not literally, lol ].
A flagpole 40ft stands on top of a building. The angle of elavation for the top of the pole is: 54 degrees 54' and the angle of elevation for the bottom of the pole is 47 degrees 30'. How high is the building?
tan 54 54' = 40
and then did tan 47 30' = 40
and subtract that and get a difference of 8.54.
Is that how you find the height of the building?
