From the top of a light house, the angles of depression of two ships on the opposite sides of its are observed to be `alphaa n dbeta` . If the height of the light house be h metres and the line joining the ships passes through the foot of the light house, show that the distance between the ship is `(h(tanalpha+tanbeta)/(tanalphat a nbeta)`
