I am unsure how to draw the angle in question 1 b) as I have seen many different ways and resulting answers. I am also not sure how to express question 2 as a bearing as my teacher says I am doing it incorrect

1. Convert the following vectors to Cartesian form. a. 13 m on a bearing of 1650 b. 120 km/h 20 West of North 2. Convert the following vectors to direction/magnitude form, giving the direction as a bearing. a. [12, 5] b. [-31, -11]
