Vector V1 is 6.29 units long and points along the negative x axis. Vector V2 is 4.23 units long and points at +35.0° to the +x axis.

(a) what is V1x & V1y

(b) what is the magnitude & direction (degrees)

    you can do this. You have the x,y component of them added.
    magnitude=sqrt(x^2+y^2)

    angle=arctan y/x

    but whats my X & Y

    V1x=-6.29 V2y=0
    V2x=4.23cos35 V2y=4.23Sin35

    Do you need a tutor? Surely there are example problems in the text. This is very basic problems.
