Anyone please help
Thank you

7) A person starts at the origin. First, he walks 20 m in the direction 60° above the +x axis. Thern he stops, turns 130° counter-clockwise, and walks 30 m. a) Draw a picture that shows the persons the path and final position. Be as accurate as possible b) At the end of his walk, what is the persons position (in component form). c) At the end of his walk. how far is he from where he started?
