Can you help me with magnitude and direction of vectors?

1) The magnitude and direction of vectors u and v are given. Find vector w's polar coordinates


u: magnitude 30, bearing 215 degree


v: magnitude 30, bearing 110 degree


w: 3u - v





a) w: (17, 149degree)


b) w: ( 193, 232 degree)


c) w: (102 231.5 degree)


d) w: ( 29, 185 degree)








2) The magnitude and direction of vectors u and v are given. Find teh vector w's polar coordinates.


u: magnitude 10, bearing 30 degree


v: magnitude 25, bearing 120 degree


w: 8u+3v





a) w: ( 99, 56 degree)


b) w(312, 63 degree)


c) w ( 110, 73 degree)


d) w (890, 42 degree)





Thank you
