Explanation:
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°
