From the top of a cliff 150m high, the angles of depression of two boats are 60degree and 30degree. Find the distance between the boats if they are on the opposite sides of the cliff.

Question

anonymous · Answer

we can solve this by simple triangle formulas... 

let's consider h= height of cliff
                    a= the distance of boat 1 from cliff
                    b= the distance of boat 2 from cliff

then since anlges are given,

we can get a & b in terms of h and get the ans as a+b
