A, B and Care stations on a straight level line of bearing 110° 16' 48". The distance AB is 314.12 m and BCis 252.58 m. With instrument of constant height of 1.40 m, vertical angles were successively measured to an inaccessible up station E as follows: At A: 7° 13' 40" At B: 10° 15' 00" At C: 13° 12' 10" Calculate: (a) the height of station E above the line ABC (b) the bearing of the line AE (c) the horizontal distance between A and E.
