Q. 41 C4.7( 3 Votes )

Two men are on the opposite sides of a tower. They measure the angles of elevation of the tower as 25° and 40° respectively. If the height of the tower is 35 m, find the distance between two men; having given tan 25° = 0.4663 and tan 40° = 0.8391.

Answer :

In right Δ ABP, we have

x = 75.058 m

x = 75.06

In the right Δ ABQ, we have

y = 41.71 m

So, the distance between two men = x + y

= 75.06 + 41.71

= 116.77 m (approx.)
