[Trigger] condition with facing angles of units

[masterbielski]

i know that it might be simple but i haven't managed to do it
i need a condition in my trigger that if units A is facing unit B with a tolerance of 30 degrees than condition is true,
the event in this trigger is that unit B is casting spell on unit A, so i tried to do it with difference of facing angles but it was too complicated for me
