Best to post your working. From a quick sketch, C is North and a bit West of A, so the bearing of A from C must be ~160 though thats a guestimate.

For the second question, try draw out your triangle first. You will notice you can make a right angle triangle with point S and C, with the S angle being 5 degrees (we know that from question: c is 680m from S). So we know the other angle in the right angle triangle is 85 degrees (at point C). We then have a straight line where we know two angles of three, one is 85 (from triangle), and the other is 60 from 360-60 (from question). Then we can use sine or cosine rule, since we know all three angles and the length of one side.
