Write the condition that Ix + my + n = 0 may be a tangent to the circle x²+y² + 2gx + 2fy +C =0

Step-by-step explanation:

The given circle has equation

This circle has centre (-g,-f).

For the line

to be a tangent to this circle, the perpendicular distance from the center to this line must be equal to the radius of the circle.

This is given by:

We substitute the center and radius to get:

We simplify to get;

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

the answer will be b x² +x-1
