Vector (V1) is 6.3 units long and points along the negative (X) axis. Vector(V2) is 9.0 units long and points at 55 degree to the positive (X)axis.
1 What are the (X) and (Y) components of (V1) vector ?
2What are the (X) and (Y) components of(V2) vector ?
3Determine the magnitude of the sum (V1+V2).
4Determine the angle of the sum (V1+V2).
i really need a help

x = v cos theta
y = v sin theta.
Everything else is laid out for you. Just plug and chug.
To get started,
v1 = 6
v2 = 9
