Question:medium

If the foot of the perpendicular drawn from the point (2,0,-3) to the plane $\pi$ is (1,-2,0) and the equation of the plane is $ax+by-3z+d=0$ then $a+b+d=$

Show Hint

The vector connecting a point to the foot of its perpendicular on a plane is parallel to the plane's normal vector. This allows you to find the direction ratios of the normal. The foot of the perpendicular must also lie on the plane, which helps find the constant term 'd'.
