From the top of a cliff, the angle of depression of

a boat on the sea is 60o, if the top of the cliff is

25m above the sea level, calculate the horizontal

distance from the bottom of the cliff to the boat.

  • A 50√3m
  • B 25√3m
  • C 25√3m/3
  • D 25m/3
  • E √3m/25

The correct answer is C. 25√3m/3

x/25 = tan 30o

x = 25/√3 = 25√3/3
