Very good! That's how simple vector components are! Again, the angle must be with the +x-axis. So, the angle is $$150+90=240^{\circ}$$
Let us say that a vector $$\vec{A}$$ has an x-component of $$5$$ and a y-component of $$7$$. We can write this as $$A_x = 5, A_y = 7$$. We can also write this as $$\vec{A} = 5 \hat{i} + 7 \hat{j}$$.
$$\hat{i}$$ means that the number multiplying it is the x-component and $$\hat{j}$$ means that the number multiplying it is the y-component. In the next module, you will see why this notation is useful.
