Step 1:

\

The vectors are $\"\"$ and $\"\"$ .

\

The dot product of the vectors $\"\"$ and $\"\"$ is,

\

$\"\"$ .

\

The dot product of the vectors $\"\"$ and $\"\"$ is

\

$\"\"$

\

$\"\"$ .

\

Angle between the vectors is $\"\"$

\

The magnitude of vector $\"\"$ is $\"\"$

\

$\"\"$

\

The magnitude of vector $\"\"$ is $\"\"$

\

$\"\"$

\

Angle between the vectors is $\"\"$

\

$\"\"$

\

Solution:

\

The dot product is $\"\"$ and angle between the vectors is $\"\"$ .
