The equations plane are $\"\"$ and $\"\"$ .

Normal vectors corresponding to the plane equation can be considered as $\"\"$ and $\"\"$ .

Dot product of two vectors $\"\"$ and $\"\"$ is defined as $\"\"$ .

Find the dot product of $\"\"$ and $\"\"$ .

$\"\"$

Since $\"\"$

$\"\"$

Thus, the normal vectors $\"\"$ and $\"\"$ are perpendicular to each other and the corresponding planes are also perpendicular.

$\"\"$

The plane of equations are perpendicular to each other.
