The magnitude and direction of vectors u and v are given. Find vector w's polar coordinates.
u: magnitude 136,. bearing 220°
v: magnitude 197, bearing 300°
w: 2u - v

Below are the possible solutions, but I cannot figure out how to enter them in a graphing calculator or a polar coordinates calculator online. Can anyone help out and show me how to get to one of the solutions so I have a better understanding of how to do them?

(223, 104°) (104, 223°)
(180.8, 307°) (307, 180.8°)
