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)

The equation of a tangent to the circle with centre (2, -1) is 3x + y = 0 . Twice of the square of the length of the tangent to the circle from the point (23, 17) 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

Write down the equation of the tangent to the circle x^(2)+y^(2)-3x+10y=15 at the point (4,-1)

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