Find all solutions (answer in radian) sqrt(3)tanx=-1

Can some please explain how to do this?

http://faculty.eicc.edu/bwood/trig_info/specialtriangles.gif Special Triangles I believe. simplify so you only have tanx = -1/sqrt(30. Locate it on the special angle by function tan (soh cah toa) and there's your angle.

I meant tanx = -1/sqrt(3)* and special triangle not angle

Also, pay attention to the minus sign. You may use the fomula tan(-x) = -tan(x).
