Sure Jeff,
It’s a bit hard to see, but there are 3 Vertices Selected and Merge at Last merges them at the last Selected, the Active (white) Vertex. That makes the Triangle go away in a simple way.
You can get good results with Sliding Vertices as well, but in this case, this seems easier to me. Call it ‘intuition through experience’, or somehthing like that.
Like we mentioned before, the Topology is extremely messy (a lot of ‘double Vertices’ as well, by the way) and we can try and make the most offending areas slightly less offending and there are different ways to do that. Whatever works to get a decent looking Render.
A real fix, would mean a complete Retopology, or just Model it yourself, but I understand, that that’s not really an option here.
