13 In the following cases, determine whether the given planes are parallel or perpendicular, and in case they are neither, find the angles between them.
(a) 7x + 5y + 6z + 30 = 0 and 3x – y – 10z + 4 = 0
whose direction ratios are and whose direction ratios are ,
are said to Parallel:
And the angle between is given by the relation,
So, given two planes
So, applying each condition to check:
Clearly, the given planes are NOT parallel.
Clearly, the given planes are NOT perpendicular.
Then find the angle between them,
