From a point on the ground, the angle of elevation of the top of a tower is observed to be 60 degree. From a point 40m vertically above the first point of observation, the angle of elevation of the top of the tower is 30 degree. Find the height of the tower and its horizontal distance from the point of observation
Let Point B is above point A 40 meter
AB = 40 m
putting value of AP in (1)
Length of the tower (PQ )= PR + QR = 40 + 20 = 60 m
Distance of tower feet from point A = AP
AP =
