If the observer is on his building of height 20 meters (including observer) and he observes the angle of depression of two ships as 45° and 60° respectively.

On the basis of above information answer the following questions.

Q. At a time when a person observes two ships whose angle of depressions are 60° and 45° the distance between the ships is (in meter).

(8.45)

Distance between two ships 20 m = BC – AC = 20 – 11.55 = 8.45 m
