Problem on sine rule Type:-2 (i)The angle of elevation of the top of the tower from a point A due South of the tower is `alpha` and from B due east of the tower is `beta`. If `AB=d` Show that the height of the tower is `d/(sqrt(cot^2alpha+cot^2beta))` (ii) A tree stands vertically on a hill side which makes an angle of `15^@` with the horizontal. From a point on the ground 35m down the hill from the base of the tree ; the angle of elevation of the top of the tree is `60^@` .find the height of the tree ?
