The angle of elevation of the top of a pillar at any point A on the ground is 15∘ . On walking 100 ft. towards the pillar, the angle becomes 30∘. Height of the pillar and its distance from A are _______ and _______ respectively.
Two pillars of equal heights stand on either side of a road which is 100 m wide. At a point on the road between the pillars, the angles of elevation of the tops of the pillars are 60∘ and 30∘. Find the height of each pillar and position of the point on the road. [Take √3=1.732] [3 MARKS]
