Wonderful! You are getting the hang of it!

Remember the angle must be with the +x-axis, not any other axis. The vector is making an angle of \(150^{\circ}\) with the +y-axis. So, it makes an angle of \(150+90=240^{\circ}\) with the +x-axis.
What is the value of \(A_y\), the y-component of vector A?
  • \(10 \sin 150^{\circ}\)
  • \(10 \cos 150^{\circ}\)
  • \(10 \sin 240^{\circ}\)
  • \(10 \cos 240^{\circ}\)
