Deduce the equations of the tangents to the circle from the point (1,0).

The equation of the circle $\displaystyle (x-2)^2+(y-2)^2=9$

my problem is that the are no tangents to the circle through the point. I got the polar of the point, $\displaystyle 2y+x+3=0$ but i don't know how to continue.

Thanks
