Solving Motion in a Plane: Find Velocity at t=7.6s

[tag16]

A particle experiences a constant acceleration that is south at 2.3 m/s2. At t = 0, its velocity is 43.4 m/s east. What is its velocity at t = 7.6 s?

I got 60.8 m/s but it also asks for the direction in degrees and I'm not sure how to find that.

Dividing the y by the x will give you the tangent of the angle

(and remember that the angle increases anticlockwise! )
