Asked by Abi

A radio tower is located 100 meters from a building. From a window in the building, a person determines that the angle of elevation to the top of the tower is 43 degrees, and the angle of depression to the bottom of the tower is 31 degrees. How tall is the tower?

Did you draw a diagram? If so, then it should be clear that the height is
100 tan43° + 100 tan31°
