In the following exericise determine whether the given planes are parallel or perpendicular and in case they are neither, find the angle between them.

7x +5y +6z+ 30 =0 and 3x -y- 10z+ 4=0

2x+y+3z-2=0 and x-2y+5=0

2x- 2y+ 4z+ 5= 0 and 3x- 3y+ 6z- 1= 0

2x-y+3z-1=0 and 2x-y+3z+3=0

4x+8y+z-8=0 and y+z-4=0
