If `y = 3x` is the tangent to a circle with centre `(1, 1)`, then the other tangent drawn through `(0, 0)` to the circle is

If 3x+y=0 is a tangent to a circle whose center is (2,-1), then find the equation of the other tangent to the circle from the origin.

The angle between the tangents to the circle with centre (4,5) drawn from P(-2,-3) is 120^(0) then length of the tangent to the circle from P is

Equation of a tangent to the circle with centre (2,-1) is 3x+y=0 .The square of the length of the tangent to the circle from the point (3,-3)

Equation of a tangent to the circle with centre (2,-1) is 3x+y=0 .The square of the length of the tangent to the circle from the point (3,-3)
