Q. 1

Find the angle between the line and the plane

Answer :

Given - and


To find – The angle between the line and the plane


Direction ratios of the line = (1, - 1, 1)


Direction ratios of the normal of the plane = (2, - 1, 1)


Formula to be used – If (a, b, c) be the direction ratios of a line and (a’, b’, c’) be the direction ratios of the normal to the plane, then, the angle between the two is given by
