1. The problem statement, all variables and given/known data Finn is lost in the woods, trying to find his way back home which he knows is 7.00 km at a 120.0° angle from his current location. He decides to travel 2.00 km at a 40.0° angle followed by another 5.00 km at a 100° angle. 1) What is his current location using a km coordinate plane system and assuming that (0,0) was his starting location? 2) Using information from the previous question, what new vector should Finn plot to get himself home? 2. Relevant equations 3. The attempt at a solution 1) current location: 2cos40 + 5cos100 = 0.664 2) new vector: 7cos120 - 0.664 = -4.16 can someone please explain to me why you use cosine and those specific numbers together?
