Find the equations of the tangents to the circle x^2 + y^2 = 169 at (5, 12) and (12, -5) and prove that they cut at right angles. Also find their point of intersection.

Find the equations of the tangents to the circle x^2 + y^2 = 169 at (5, 12) and (12, -5) and prove that they cut at right angles. Also find their point of intersection.

The tangtnts to the circle x^(2)+y^(2)=169 at the point (5,12) and (12,-5) are

The point (1,2) lies inside the circle x^(2) + y^(2) - 2x + 6y + 1 = 0 .

The point (1,2) lies inside the circle x^(2)+y^(2)-2x+6y+1=0 .

If the point (3,4) lies inside and the point (-3,-4) lies outside the circle x ^(2) + y ^(2) - 7x +5y -p=0, then the set of all possible values of p is
