Lighthouse

Here is a classic question, given the height of a lighthouse (PQ), the bearings of two ships and the respective angle of depression, can you find the distance between the two ships (ST)? The bearings and the angles of depression can be adjusted, the view can also be rotated. Try the top view and some side views to reveal the triangles that need to be solved.
