  1. The respective ratio between the height of tower and the point at some distance from its foot is 535: . What will be the angle of elevation of the top of the tower?
    1. 30°
    2. 60°
    3. 90°
    4. 45°
Correct Option: B


AB = Tower
BC = distance of point C

tanθ =
AB
=
5√3
= √3
BC5

∴ tanθ = tan60°
⇒ θ = 60°
