Surveying The difference of levels between two stations A and B is to be determined. For best results, the instrument station should be equidistant from A and B closer to the lower station closer to the higher station as far as possible from the line AB equidistant from A and B closer to the lower station closer to the higher station as far as possible from the line AB ANSWER DOWNLOAD EXAMIANS APP

Surveying When a star is between the pole and the horizon, the relationship between latitude (λ), zenith distance (z) and declination δ, is θ = 180° - (z + δ) θ = (z + δ) - 180° θ = z + δ θ = δ - z θ = 180° - (z + δ) θ = (z + δ) - 180° θ = z + δ θ = δ - z ANSWER DOWNLOAD EXAMIANS APP
