1)A force vector points at an angle of 12.4 ° above the +x axis. It has a y component of +337 newtons (N). Find the magnitude and the x component of the force vector.
For the x component I did 337cos(12.4)=329.13 N
For magnitude I am not sure what to do.
sinα =F(y)/F => F =F(y)/ sinα,
tan α = F(y)/F(x) => F(x) =F(y)/tanα.
