Lets get some more practice finding the angle in this in these cases the positive angle between the positive x-axis and a vector drawn in standard form where its initial point or its tail is sitting at the origin and so here for vector AI we can we can write it in two different ways in engineering notation it would be negative two times a unit vector I - thats the unit vector in the X Direction minus four times the unit. The vector F x is in the opposite direction as the x-hat vector and that is why you need a negative sign.
