Given at the time of observation, GHA = 104 57' 05.9"; declination = 22 13' 03.4"; Occupied point A with Latitude 42 45' 10" N and Longitude 112 25' 54" W. Clockwise angle at A from backsight point P is 150 45' 12". Calculate astronomic azimuth of line AP. There is no need to apply the sun's semi-diameter correction
