Question:
The distance of point P (3, 4, 5) from the y z-plane is
(A) 3 units
(B) 4 units
(C) 5 units
(D) 550
Solution:
(A) 3 units
Explanation:
From basic ides of three-dimensional geometry, we know that x-coordinate of a point is its distance from y z plane.
∴ Distance of Point P (3, 4, 5) from y z plane is given by its x coordinate.
∵ x-coordinate of point P = 3
∴ Distance of (3, 4, 5) from y z plane is 3 units
Hence, option (A) is the only correct choice.
