Direction ratios of the line are (2,3,6)

Direction ratio of a line perpendicular to the plane

10x + 2y – 11z = 3 are 10, 2, – 11

As we know that the angle θ between the line and a plane a₂x + b₂y + c₂z + d₂ = 0 is given by

If θ is the angle between the line and the plane, then

∴

⇒

⇒

⇒ sinθ = ⇒ θ = sin ^{– 1}(

∴ the angle between the plane and the line is sin ^{– 1}(
