[600MRG] Scopematch question

[N1BUG]

I'm embarrassed that I haven't yet found (or figured out on my own) 
an answer to this, but am going to ask...

Assuming one is using a scopematch and there is some reactance so 
one trace leads the other... is there some math that will convert 
from degrees leading or lagging to ohms capacitive or inductive 
reactance? It seems that should be readily possible but I can't 
quite get my mind around it.

I guess this could be complicated or inaccurate if the waveforms are 
distorted, but let's assume for now they're not.

Thanks, 73,
