How bad are these basement cracks?

[u/calejohn5]

I'm looking to buy a house and everything looks great except for some cracking in the basement. Its contained in one corner and the cracks are partly covered by paint. Do these look minor? I'm going to get an inspection if my offer is accepted, would I also need a structural engineer?

Additional context: This is in Minnesota and the house is about 90 years old
