Write the length of the perpendicular drawn from the point P(3, 5, 12) on x-axis.
The distance of the point P(3, 5, 12) from x-axis is given by \(\sqrt{5^{2}+12^{2}=\sqrt{169}\)=13
The length of the perpendicular drawn from the point P(3, 3, 4) from the
y-axis is
Length of subtangent is defined as the perpendicular distance between the point where the tangent is drawn and x-axis
