I want to localize node C (refer image below).Here we know the coordinates of A and B and A is in range of B and C so we can calculate the distance AC and AB using the ranging functionality. I need to calculate the distance between B and C that are not in direct range of each other.I want to use the Law of cosines, Is there a way to calculate the angle 'γ' represented in the below picture in UnetStack ?Image Ref
