Answer:
The he cosine of the angle between the planes is
.
Step-by-step explanation:
Using the definition of the dot product:

The given planes are


The angle between two normal vectors of the planes is the same as one of
the angles between the planes. We can find a normal vector to each of the
planes by looking at the coefficients of x, y, z.





The cosine of the angle between the planes



Therefore the cosine of the angle between the planes is
.
