ZLC ARTCC controller reported they were handed off an aircraft below their radar coverage on a rando...

Narrative:

A cessna caravan; not in radar coverage; was [getting] handed off to me from a center sector 10 [at] 11;000 feet direct to the ksgu airport on a random route. I attempted to contact the center sector about the aircraft as they were going through several areas of high terrain and many active military use airspaces. There wasn't an answer. Eventually they contacted me. I told them I could not take the aircraft because he was non-radar on a random direct route where no points on his path were displayable on my scope.the controller became agitated and asked me how he could fix it. I didn't have an answer; at that point; the rule had already been broken and I wasn't sure how he could fix it. He then got even angrier that he didn't know that he should have read the faah 7110.65 before he started controlling traffic; instead of asking me to explain it to him over a shout line while I was busy. I finally got the aircraft; not in radar contact; and I knew the transferring sector wasn't going to fix it; so the safest course of action was to give the aircraft to me. I made sure the aircraft was level above the highest terrain in the area and cleared him direct to a VOR within NAVAID use limitations.

Narrative: A Cessna Caravan; not in radar coverage; was [getting] handed off to me from a Center Sector 10 [at] 11;000 feet direct to the KSGU airport on a random route. I attempted to contact the Center sector about the aircraft as they were going through several areas of high terrain and many active military use airspaces. There wasn't an answer.
