You are going camping and will take four hikes. On the first day you start from your campsite and travel 5 kilometres at an angle of 27 degE of N. On the second day you will travel 18 kilometers due north. Your third hike is 12 kilometers at an angle of 20deg E of N. On the final hike you travel another 16 kilometers at 65DEg Sof E. Find your displacement from the orginal campsite, What heading should you use to return to your start point?
