Sketch a vector representing a 10 Newton force which acts vertically downward.
• Position an x-y coordinate plane so that the initial point of your vector is at the origin, and the angle of the vector as measured counterclockwise from the positive x axis is 250 degrees. This will require that you 'rotate' the x-y coordinate plane from its traditional horizontal-vertical orientation.

I think I have done it correctly not sure though.

• What are the x and y components of the equilibrant of the force?
answer/question/discussion: ->->->->->->->->->->->-> :
arctan(-y comp. / -x comp.) = 250 deg.
Don’t know how to solve???

@& You could use two simultaneous equations, the first being the equation you give, the second being x^2 + y^2 = (10 N)^2.
However you can more easily just find the x and y components of your vector (10 N cos(250 deg) and 10 N sin(250 deg)). The components of the equilibrant will be equal and opposite.*@
