The angle of elevation of the top of a tower at a distance of 120 m from a point A on the ground is 45°. If the angle of elevation of the top of a flagstaff fixed at the top of the tower, at A is 60°, then find the height of the flagstaff. [use √3=1.73]
Let AB is the tower of height h meter and AC is flagstaff of height x meter.
∠APB=45° and ∠BPC =60°
`Tan 60 = (x+h)/120`
therefore height of the flagstaff =
