14.In wandering, a grizzly bear makes a displacement of 1563 m due west, followed by a displacement of 3348m in a direction 32.0degrees north of west. What are a)the magnitude b) the direction of the displacement needed for the bear to return to its starting point? Specify the direction relative to due east.(pg 4 of notes)

2. Relevant equations

mag=squareroot of x^2 + y^2

3. The attempt at a solution

I took the x and y components of both vectors A and B. added them up took square root of x^2 and y^2 to get 4438 m. then took the inverse tan of 4438/1563 and got 70.6 degrees East. 2 questions i had was if my formula is correct in that the Magnitude = either the square root of x^2 + y^2 or is it just x^2 + y^2 and for the direction do i take the inverse tan of the x and y components like x over y or do i take the inverse tan of opp/adj which is 4438/1563? Thanks to anyone who can help me check my answer I have no where else to look.
