A.B=COS teta
COS teta=A.B​

Answer 1

pie/4 is the answer I guess.

Answer 2

Step-by-step explanation:

It is 45°. Well just apply the definition.

A×B= A B Sin(x) C^

While A.B=A B Cos(x)

Substitute in the given equation we get AB Sin(x) = AB Cos(x)

Here direction is not taken as we are dealing with magnitude only as per the condition.

Now Sin(x)= Cos(x)

Finally we get Tan(x)= 1

That is x= 45
