The angle of elevation of the top of a tower at a point A due south of the tower is `alpha` and at `beta` due east of the tower is `beta`. If AB=d, then height of the tower is

The angle of elevation of the top of a tower from a point A due south of the tower is alpha and from B due east of tower is beta . If AB=d , show that the height of the tower is d/sqrt(cot^2 alpha+ cot^2 beta) .

The angle of elevation of the top of a tower from a point A due south of the tower is alpha and from B due east of tower is beta . If AB=d , show that the height of the tower is d/sqrt(cot^2 alpha+ cot^2 beta) .

The angle of elevation of the top of a tower from a point A due south of the tower is alpha and from B due east of tower is beta. If AB=d , show that the height of the tower is (d)/(sqrt(cot^(2)alpha+cot^(2)beta))

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 ?

The angle of elevtion of the top of a tower from a point A due South of the tower is alpha and from a point B due east of the tower is beta . If AB = d, then prove that the height of the tower is (d)/(sqrt(cot^(2) alpha + cot^(2) beta))

The angular elevation of a tower OP at a point A due south of it is 60^@ and at a point B due west of A, the elevation is 30^@ . If AB=3m, the height of the tower is

The angular elevation of a tower OP at a point A due south of it is 60^@ and at a point B due west of A, the elevation is 30^@ . If AB=3m, the height of the tower is
