Ineed in my physics class and show me how it’s done

If we have the angle and magnitude of a vector A we can find its Cartesian components using the following formula

Where | A | is the magnitude of the vector and is the angle that it forms with the x axis in the opposite direction to the hands of the clock.

In this problem we know the value of Ax and Ay and we need the angle .

Vector A is in the 4th quadrant

So:

So:

So:

= -47.28 ° +360° = 313 °

= 313 °

Option 4.

the components of a vector are the parts of the vectors that are to each other.
