Answer 2

Now , what I did in the solution was using trigonometric functions to solve the question and get you the height of lighthouse which is 200(3-√3).

First I used the angles given in the question to find a relationship between the adjacent sides of the two triangles and then using the distance provided between the ships I calculated the height of lighthouse.

Hope it helps!!
