  1. The angle of elevation of a tower from a distance 50 m from its foot is 30°. The height of the tower is
    1. 50 √3 m
    2. 50
      		m
      √3
    3. 75 √3 m
    4. 75
      		m
      √3
Correct Option: B


AB = Tower = h metre
BC = 50 metre
∠ ACB = 30°

∴ tan 30° =
AB
BC

⇒
1
=
AB
√350

⇒ AB =
50
metre
√3
