How do I solve this vector problem for my phyics homework?

V is a vector 14.3 units in magnitude and points at an angle of 34.8 degrees above the negative x axis





a)find Vx and Vy


b)use Vx and Vy to obtain (again) the magnitude and direction of V.|||a)Vx=Vcos(180-34.8)=14.3cos(145.2)


Vy=Vsin(180-34.8)=14.3sin(145.2)


b) V^2=Vx^2+Vy^2
