You are trying to determine the height of a building whose base is on a level plane on which you stand. You are at the base of a vertical pole that you are able to climb. From
the base of the pole, you measure the angle to the top of the building to be 30°. You climb
a certain distance up the pole and measure again: the angle is now 28°. After climbing 10
feet further up the pole, you measure once more, and find the angle is 27º.
How tall is the building?
