so explanation
6 and 7/8+4 and 5/8=6+7/8+4+5/8=6+4+7/8+5/8=10+(7+5)/8=10+12/8=10+1+4/8=11+4/8=11+1/2
THE ANSWER IS 11 AND 1/2
The correct answer is 54.3.
(i) The bearing of B from A and angle x are supplementary, then:

(ii)
From the above diagram, the bearing angle of A from B is:

(iii)
From the above diagram, the bearing angle of C from B is:

(iv)
Applying the law of cosines with the sides AB = 145m and CB = 240 m, and the angle ABC = 68°, the distance AC is:
