The angle of elevation of the toop point...

The angle of elevation of the toop point P of the vertical tower PQ of height h from a point A ` 45^(@)` and from a point B is ` 60 ^(@)` , where B is a point at a distance 30 meters from the point A measured along the line AB which makes an angle ` 30^(@) ` with AQ . Then the height of the tower is.

Text Solution

Verified by Experts

The correct Answer is:
`15 sqrt(3) + 15 = 15 (sqrt(3) + 1)` metres.
