Question

The perpendicular distance of the point P(3, 3,4) from the x-axis is

(a) $3\sqrt{2}$
(b) 5
(c) 3
(d) 4

Answer 1

The perpendicular distance of the point P(3, 3,4) from the x-axis is given by

$$\begin{gathered} \sqrt{3^2+4^2} \\ =\sqrt{25} \\ =5 \end{gathered}$$
Hence, the correct answer is option (b)
