Enough information IS here, assuming that you have a vector emanating from the origin.
If you make a drawing, you can EASILY find the answer yourself, based the tangent ratio.

θ = arctan(5/-5) + pi ⇐because inverse tangent of a negative value is an angle in quadrant IV; must correct it to quad II.
θ = arctan(-1) + pi
θ = -pi/4 + pi = ¾•pi;
