The angle of elevation of an electric pole fora point A on the ground is `60^@` and from a Point B towards the pole on the line joining the fiof the pole to the point A, is `75^@`. If the distan `AB = a`, then the height of the pole is

The angle of elevation of an electric pole from a point A on the ground is 60^(@) and from a Point B towards the pole on the line joining the foot of the pole to the point A, is 75^(@) . If the distance AB = a, then the height of the pole is

The angle of elevation of the top of an adjustable pole from a point on the ground is 30^(@) . What will be the angle of elevation of the top of the pole if its height is tripled?

AB is a vertical pole with B at the ground level and A at the top . A man finds that the angle of elevation of the point A from a certain point C on the ground is 60^@ . He moves away from the pole along the line BC to a point D such that CD = 7 m . from D the angle of elevation of the point A is 45 then the height of the pole is

AB is vertical pole with B at ground level and A at the top. A man finds that the angle of elevation of the point A from a certain point C on the ground is 60^(@) . He moves away from the pole along the line BC to a point D such that CD =7 m. From D the angle of elevation of the point A is 45^(@) then the hight of the pole is

AB is a vertical pole with B at the ground level and A at the top. A man finds that the angle of elevation of the point A from a certain point C on the ground is 60^@ . He moves away from the pole along the line BC to a point D such that CD =7m. From D, the angle of elevation of the point A is 45^@ . Then the length of the pole is:
