                   Example 5: From a point A, the summits of two mountains,  B and C, are on
                             bearings  of 024 ' and 058 " ,  and the angles  of elevation are 8.5  " and
                             9.3  " respectively.  If B is 850 m above A, and C is due east of B,
                             Calculate
                             (a) the horizontal distance from B to A
                             (b) the height ofC above A
