Inside Corner coming away

Inside Corner coming away
We Purchased house 10 yrs. ago and house id 35 yrs. old beginning to notice a few corners coming away, they didn’t look like that when we purchased. So, wondering what best way to repair as they all seem to be about way down the wall. Sorry for some reason it will only post picture sideways.

Cut out the existing tape, especially any bulges, and install new mud/tape. Add another two coats to the corner, sand and paint.

If new to taping be sure to get plenty of mud under tape. when you run knife over it mud will squeeze out but it need mud to stick.
