Answer:

Step-by-step explanation:

The direction of the vector implies only its angle, not its magnitude. The direction of the vector is found in


tan^(-1)((y)/(x)) so


tan^(-1)((11.1)/(-43.0))=-14.5 but since we are in QII (where x is negative and y is positive) we have to add 180 to this number to get a direction of 165.5 degrees
