So I've worked out part (a) - just not (b) as I don't understand how it can be measured from due east. I don't want it worked out for me, just help me understand this due east business. I can't see how it can be anything but due west... Background: Orienteering teams are operating in a densely forrested area.The GPS at their base shows the location of team A as 78.2 km away, 14° north of west, and team b as 231 km away, 59° east of north. When team A uses its GPS to check the position of the team b, what does it give for the team b's (a) distance from them and (b) direction, measured from due east? 2. Relevant equations Resolving vectors into components 3. The attempt at a solution I know how to do this question except when it gets to: direction from due east. It seems that B's team could be measured from A, but this would be the due West right? hmmmmm... can someone help? thanks:) The image below was constructed to show that theta could be from B team near east... I don't know it will show you an insight anyway... [URL]http://www.flickr.com/photos/40253561@N06/4910222024/[/URL] Thank you so much!
