please help with advise

my back right wheel looks like it is pushed inward at the top. it is not the rim that is bent it is the wheel is a little diangle. it drives smooth without any wobble, but it does pull to the right. the a arm looks all straight, would this just be a bent strut? whatever did this to my car dose not look like it hit hard.

Well, it would really be handy if we knew the make, model and year........

Lets assume it does have struts in the back.
If it suffered an impact, the strut may be bent, spindle bent, chassis damaged or just the bolts that hold the strut to the knuckle are loose, allowing the strut to shift.
Regardless, take it to an alignment shop. They can tell you what's wrong and what's required to fix it.
