amistre64 · Answer

you did right to add the vectors ... just right them up in their respective cos sin parts

hiroromon · Answer

like what is velocity? how do i find it? i know how to find the magitude and stuff i just don't know the formula for getting velocity

amistre64 · Answer

180 - 50 = 130


    45 cos(130) X + 45 sin(130) Y
+ 10 cos(-45) X + 10 sin(-45)  Y
-----------------------------
             resultant (X,Y)

amistre64 · Answer

the magnitude of the resultant will be the magnitude

amistre64 · Answer

or we can walk a law of cosines if you just want the magnitude of the resultant

hiroromon · Answer

why did you use 130 to find the velocity?
