Best ResponseYou've already chosen the best response.0Initially I thought it would be 2240  360*360*... until the degree is less than 360. But then I got 80... Based on the book's picture it should be 240

Best ResponseYou've already chosen the best response.1It is 240 degrees. It's given as (2, 240). It's two different numbers: 2 is the length of the vector, and 240 degrees is how much it's rotated from the positive x direction.
