A radio tower is located 450 feet from a building. From a window in the building, a person determines that the angle of elevation to the top of the tower is 29 degrees and that the angle of depression to the bottom of the tower is 22 degrees. How tall is the tower?

the height h is
h = 450tan29° + 450tan22° = 431 
thank you!!

once you draw a diagram and label the known data, the solution just becomes clear.
