If the angles of elevation of a tower from two points distance a and b (a > b) from its foot and in the same straight line from it are 30° and 60°, then the height of the tower is?

Let AB be the tower and P and Q are such points that PB = a,
QB = b and angles of elevation at P and Q are 30° and 60° respectively
