Answer by josgarithmetic(39630)   (Show Source):
You can put this solution on YOUR website! For points the point on ground away from the hill, the top of tower, the bottom of tower, form a triangle. Best if you draw the whole description.
This upper triangle has angles
top of tower, 61 degree 58 minute
bottom of tower, 28 degree 2 minute
Length between these is 45 meter.
Angle opposite this is 5 degree 16 minute.
Use that to continue, and to finish. (More steps left undone here).
(A more efficient way may be possible.)
