An object acted on by three forces moves with constant velocity.?

One force acting on the object is in the positive x direction and has a magnitude of 6.0 N ; a second force has a magnitude of 4.3 N and points in the negative y direction part a Find the magnitude of the third force acting on the object.

part a
Find the magnitude of the third force acting on the object.
Express your answer using two significant figures.

part b
Find the direction of the third force acting on the object.
Update: Part C

An object of mass 6.15 kg has an acceleration a⃗ =(1.49 m/s2 )x^+(-0.698 m/s2 )y^.

Three forces act on this object: F⃗ 1, F⃗ 2,and F⃗ 3.Given that F⃗ 1=(3.56 N )x^ and F⃗ 2=(-1.56 N )x^+(2.16 N )y^, find F⃗ 3.
Express your answers using three significant figures separated by a comma.
