# Write the distance of a point P(a, b, c) from x-axis.

Answer :

Given,

The point is (a,b,c). Let this point be P.

From the figure, point E (a,0,0) is the projection of point P(a,b,c) on the x-axis.

The distance between the points P & E will give the distance of the point P from x-axis.

__Distance between two points is given by__

Here

a_{1} =a , b_{1} =b , c_{1}=c and a_{2} =a , b_{2} =0 , c_{2} = 0

Distance between P and x-axis is

Therefore the distance between, the x-axis and the Point P (a,b,c) is units.
