Question

Write the distance of the point (3, −5, 12) from X-axis?

Solution

\[ \text { The distance of a general point } \left( x, y, z \right) \text{ from  x - axis is } \sqrt{y^2 + z^2} . \]

\[ \therefore \text{ Distance of the point } \left( 3, - 5, 12 \right) \text{ from x - axis }= \sqrt{\left( - 5 \right)^2 + {12}^2} \]

                                      \[ = \sqrt{169} \]

                                      \[ = 13 \text{ units }\]
