Can you please help me answer number24?

Problem 24: (first taught in lesson 60) To get to her friend's house, Sandra walked along the sidewalk in her neighborhood. If she walked 100 yards at a direction 450 north of east and then turned to walk 400 yards straight east, how many yards and in what direction would she need to walk if she wanted to walk straight home without having to make any turns? Round any irrational answers to one decimal place. After you enter your answer press GO. yards D south of west GO Playback W
