T rex did use its arms for a few purposes unlike popular belief.Here are the uses their arms had.

 T-rex would use its arms to help it rise after sleeping, along with using them as ‘Hooks’ To grab hold of food while it used its incredibly strong jaws to rip massive amounts of flesh off a carcass. The arms themselves, to put it simply, were jacked.

Its short, strong forelimbs and large claws would have permitted T. rex, whether mounted on a victim’s back or grasping it with its jaws, to inflict four gashes a meter  or more long and several centimeters  deep within a few seconds’
