Answer:
To me, it looks like it should already be eligible for SAS.
Step-by-step explanation:
SAS stands for Side, Angle, Side (what items have to be congruent for this method to work.)
As we look at the picture, there are two sides equal, and an angle between them.
So, it looks like SAS is already viable to use, without having to add more information! (at least from what I can say.)
Sorry about my poor answer, I'm in a Zoom Class right now.
