Asked by akhileshnarayanan | 10th Feb, 2010, 09:47: PM
Dear Student
the angles of depression of first kilometres stone 450
Say height of the tower =h
the distance between the tower wnd the first kilometer stone =x
the angles of depression of first kilometres stone 450
tan 45= h/x ===> 1=h/x ==> h=x----(1)
tan (30)= h/(x+1)= h/(h+1)
h/(h+1)= 1/3 ===> h(1+ 1/
3 ) =1/
3
h= 1/(1+3)
