Trigonometric levelling was used to measure the height of the point P from the point A, see the survey situation. The height of the point A is hA= 50 m. The horizontal distance is d = 800 m and the zenith angle is a = 50⁰. The accuracy of the point A is characterized by the standard deviation of ±0.6 cm. The standard deviation of the measured slope distance is ±7 cm. The standard deviation of the measured zenith angle is ±2". d hp = ? a hA A Compute the height of the point P and its standard deviation.
