Find the direction angle using the give information

Find the magnitude and positive direction angle of the vector -3/3,-3). The magnitude of the vector is 6 Simplify your answer.) The direction angle is° (Simplify your answer.)

Solution

since the coordinates are in 3rd quadrant

direction angle for 3rd quadrant is givenn by

pi - tan^-1 ( - 3 / - 3 sqrt 3 )

direction angle = -150 degrees
