from a point o in the school compound, adeolu is 100m away on a bearing of N35 degrees east and Ibrahim is 80m away on a bearing of South 55 degrees west. how far apart are both boys and what is the bearing of Ibrahim from adeolu in three figure bearings?

Answer 1

Draw a diagram, and use the law of cosines to find the distance.
Then, using the point given, find the locations of the two boys. If they are at locations (a,b) and (c,d) then the bearing of Ibrahim is SθW where
tanθ = (a-c)/(b-d)
