Get Angle between actors?

Hi, I’m trying to figure out how to get the angle between two actors by 2D. I’ve been playing with the Find Look at Rotation but am getting lost in how to convert the rotator into what I want. So in the ref image, the angle by this calc between Actor A and B would be 43. I don’t really care where 0 (360) sits, I just want to be able to find relative world location between the actors based on the angle.
