- A bird is resting on a point P at a height of 8 m above the Mean Sea Level (MSL). Upon hearing a loud noise, the bird flies parallel to the ground surface and reaches a point Q which is located at a height of 3 m above MSL. The ground surface has a falling gradient of 1 in 2. Ignoring the effects of curvature and refraction, the horizontal distance (in meters) between points P and Q is ______ (in integer).

- 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).

- To reduce the slope distance (S) to an equivalent horizontal distance (H) as shown in the figure given below, the following independent observations were taken.
\(S = 29.95 m ± 0.01 m; \theta = 4°30' ± 10' \)
The required precision of computed horizontal distance is ± 0.005 m. Assume a "balanced accuracy" where the contribution to precision of the horizontal distance comes equally from the slope distance and angle measurements. The minimum number of angle observations to achieve the desired precision is
