If `x=3` is the chord of the contact of the circle `x^2 + y^2 = 81,` then the equation of the corresponding pair of tangents, is

If x = 9 is the chord of contact of the hyperbola x^2-y^2=9 , then the equation of the corresponding pair of tangents is :

If x= 9 is the chord of contact of the hyperbola x^2-y^2=9 , then the equation of the corresponding pair of tangents is :

Let H : x^(2) - y^(2) = 9, P : y^(2) = 4(x - 5), L : x = 9 be three curves. If L is the chord of contact of the hyperbola H, then the equation of the corresponding pair of tangent is

Let H : x^(2) - y^(2) = 9, P : y^(2) = 4(x - 5), L : x = 9 be three curves. If L is the chord of contact of the hyperbola H, then the equation of the corresponding pair of tangent is

If x=9 is the chord of contact of tangents of x^(2)-y^(2)=9 , then show that the equation of corresponding tangents is 9x^(2)-8y^(2)-18x+9=0
