the direction is approximately what if the magnitude is approximately 4.12, how do I find the direction?

The x- and y-coordinates of a moving particle are given by the parametric equations below. Find the magnitude and direction of the velocity for the specific value of t. Sketch the curve and show the velocity and its components. x - 4t, y -4-t, t=3 Find the magnitude of the velocity of the particle for the specific value of t. The magnitude is approximately 412 (Type an integer or decimal rounded to two decimal places as needed ) Find the direction of the velocity of the particle for the specific value of t. Enter an angle ( such that U" s 0
