Hello everyone. I use Bio Savar's law to determine the intensity of the magnetic induction vector.

I use this formula

R is distance of wire from point in which I calculate intensity of the magnetic induction.

How can I known which angle is positive and which angle is negative from this two angles.Which is a general rule?
