The number of lines that can be drawn through the point P at a distance of d meters from the point Q if are
Draw a circle having centre at P and radius d meters.
If the point Q lies inside the circle then the lines drawn through the point P at a distance of d units is zero.
If the point Q lies on the circle then the lines drawn through the point P at a distance of d units is one.
If the point Q lies outside the circle then the lines drawn through the point P at a distance of d units is two.
Here,
It means the point Q lies outside the circle
Therefore, the number of lines drawn through the point P at a distance of d units is two
