A man standing at a point P is watching the top of a tower, which makes an angle of elevation of 30° with the man's eye. The man walks some distance towards the tower to watch its top and the angle of the elevation becomes 60°. What is the distance between the base of the tower and the point P?

Answer:
Distance between the base of the tower and the point P is the time's distance traveled by the man
Step-by-step explanation:
Recall the values:
tan 30° =
tan 60° = √3
Solution:
Let 'A' be the foot of the tower and 'h' be the height of the tower, then from the diagram we have AB = h.
Let 'x' be the distance between the foot of the tower and the point 'P'
and 'y' be the distance traveled by the man
From the ΔPAB,
tan 30 =
Substituting the values we get,
=
√3H = x
H = --------------(1)
Again from ΔQAB,
tan 60 =
√3 =
H = √3(x-y) ---------------(2)
From equations(1) and (2) we get
√3(x-y) =
3(x-y) = x
3x -3y = x
2x = 3y
x =
AP = X distance traveled by the man
∴ Distance between the base of the tower and the point P is the times the distance traveled by the man
