How to rdp into a pc that is on USB tethering?

Question

I have a pc1 and a phone that are connected to a router/internet. I have a pc2 that is using the above phone to get internet using USB tethering.

The pc2 ip is 192.169.42.234, which doesn't match the network 192.168.1.x

I would like to rdp from pc2 into pc1, how can I do that?
