Question

Find the direction ratios of the normal to the plane

Answer 1

Hey friend here is your answer.

The direction ratios of the normal to the plane are 2, -1, 3. Angle between the planes is defined as angle between normals of the planes drawn from any point to the planes. Note: If a1a2 +b1b2 +c1c2 = 0, then the planes are perpendicular to each other.

Hope it would help.
