The angle of elevation of the top of a tower at a point on the ground is 30o.On walking 24m towards the tower,the angle of elevation becomes 60_(0). Find the height of the tower.

The angle of elevation of the top of a tower at a point A on the ground is 30^(@) . On walking 20 meters toward the tower, the angle of elevation is 60^(@) . Find the height of the tower and its distance from A.

The angle of elevation of the top of a hill from a point on the horizontal planes passing through the foot of the hill is found to be 45^(@) . After walking a distance of 80 meters towards the top , up a slope inclined at an angle of 30^(@) to the horizontal plane , the angle of elevation of the top of the hill becomes 75^(@) . Then the height of the hill ( in meters ) is _________
