1. One morning, Connie walks from her house to go to a store that is 500 ft, S 40° W from her house. She starts walking 120 ft, SW; then continues walking 100 ft, 10° S of E; then sees a friend who is 700 ft, 30° N of E from where she is. a) What is her friend's location, (magnitude and direction) relative to her house? (Ans. 667.54 ft, 21.79° N of E) b) From her friend's location, how far and in what direction should Connie walk to finally get to the store? (Ans. 1133.08 ft, 33.83°S of W)
