Determine the direction angles

Reference no: EM13293373

Using a theodolite, with a laser rangefinder, a researcher at point A locates a pair of rare birds nesting at point B and determines the direction angles ??=53d, ??=38d, ??=81d and distance 242m for a position vector from point A to B. For subsequent observations. the researcher would like to use position C, and thus while at point A, she also measures the direction angles ??=142d, ??=63d, ??=65d and distance 309m for a direction vector from point A to C. For observation from point C, determine the direction angles and distance to the nest at B.
