Could you please explain it further @kc_kennylau

anonymous · Answer

are you sure it's standing due south of the tower and not west or maybe east? because if the man was initially standing due south of the tower then the angle of elevation of the top of the tower would be zero wouldn't it

I got 22.61degrees following your graph @kc_kennylau but it turned out wrong

now if the man were to move 120 m due to east it would be|dw:1385298992080:dw|
the angle we would be looking for would be the angle of depression of the top of the tower
