I do not have a good understanding of black holes or any equations to do with them really, but I saw that an equation called the Schwartzchild Radius can be used to calculate the radius an object needs to be compressed to if it were to be made into a black hole. The equation was Rs=2GM/c^2 and I wondered whether one could use this equation along with the radius of the supermassive black hole at the center of our galaxy to approximate the mass of the object that created/was the predecessor to the black hole. As mentioned before I dont have a clue about black holes and this may be nonsense but I was just curious. Sorry this is so long, Thanks

Yes, but it will give you the mass of the SMBH now and not the mass of the thing that created it. The Schwartzchild radius tells you the event horizon of a black hole.

Yeah, the SR tells you the distance an object travelling at the speed of light has to be from a black hole to escape it.
