The locus of the mid-point of the chord of contact of tangents drawn from points lying on the straight line 4x - 5y = 20 to the circle $${x^2}\, + \,{y^2} = 9$$ is

$$20\,({x^2}\, + \,{y^2}) - \,\,36x\,\, + \,\,45y = 0$$

Tangents drawn from the point P (1, 8) to the circle $${x^2}\, + \,{y^2}\, - \,6x\, - 4y\, - 11 = 0$$ touch the circle at the points A and B. The equation of the cirumcircle of the triangle PAB is

$${x^2}\, + \,{y^2}\, - \,4x\,\, - 10y\, + 19 = 0$$
