Geomatics Engineering Question on Distance and angle measurement
In tangential method of tacheometry, two vanes in a staff were fixed at a distance of 1.0 m with the bottom vane fixed at 1.0 m. The levelling staff was held vertical at a point P and the vertical angles of the vanes observed were 5°30′ and 3°15', respectively. The vertical distance between the instrument axis and the bottom vane would be _______ m (rounded off to two decimal places).
Answer
The correct answer is : 1.40 to 1.50 (approx.)
