Question

L is the foot of the perpendicular drawn from a point P(6,7,8) on the X Y-plane, then the coordinates of point L are (A) (6,0,0) (B) (6,7,0) (C) (6,0,8) (D) None of the above

Since, L is the foot of perpendicular from P on the X Y-plane, Z-coordinate is zero in the X Y-plane. Hence, coordinates of L are (6,7,0).

Q. $L$ is the foot of the perpendicular drawn from a point $P (6, 7, 8)$ on the $X Y$ -plane, then the coordinates of point $L$ are

$(6, 0, 0)$

$(6, 7, 0)$

$(6, 0, 8)$

None of the above

Since, $L$ is the foot of perpendicular from $P$ on the $X Y$ -plane, $Z$ -coordinate is zero in the $X Y$ -plane. Hence, coordinates of $L$ are $(6, 7, 0)$ .
