Write the distances of the point (7, −2, 3) from XY, YZ and XZ-planes.
उत्तर
The distance of a general point P (x, y, z) from XY−plane is z.
Thus, distance of (7, −2, 3) from XY−plane is 3.
Similarly, the distance of P (x, y, z) from YZ−plane is x.
Thus, distance of (7, −2, 3) from YZ− plane is 7.
The distance of P (x, y, z) from XZ−plane is y.
Thus, distance of (7, −2, 3) from XZ−plane is 2 .
