in an orienteering exercise, a team hikes 8k from the starting point, s, on a bearing of 300 degrees then 6 km on a bearing of 040 degrees to the finishing point F. Find the magnitude and direction of the displacement from S to F.
My efforts: I draw a diagram. From it I took, x/sin 20 = 6/sin60
x= 2.37 km but the answer in the book is 9.13 km why??????////////
