The distance of the point P(a ,\ b ,\ c)...

The distance of the point `P(a ,\ b ,\ c)` from the x-axis is a. `sqrt(b^2+c^2)` b. `sqrt(a^2+c^2)` c. `sqrt(a^2+b^2)` d. none of these

Text Solution

Verified by Experts

the coordinates of point on X-axis is ` (a,0,0).`

` therefore,` distance of the point from x-axis `=sqrt( (a−a)^2+(0−b)^2+(0−c)^2)`

`=sqrt(b^2+c^2)`
