Answer : Distance of plane from a given point =0.408
Explanation:
Since the equation of plane is x-y+2z-2=0
and the given point is (1,2,1)
And we know the formula of distance of plane from a point
i.e.
D=
where A,B,C are the coefficient of x, y, z respectively ,
and are the given points .
So,
=
Now by using calculator we can find the value of √6 i.e. 2.449 upto three decimal places.
∴ Distance = 0.408
