Does this structure look safe/normal?

When I was looking around the attic yesterday, I notice the main enormous beam (probably not the proper term for it!) that holds the main part of the roof up (its an L shape roof), is only held in by bricks and mortar on one side. There is a similar sized beam that meets it at 45 degrees on the other side, but I just wanted to check if it looks normal and safe to be balanced like that!

That’s not going anywhere 

The second picture with the wedge under it looks like it’s running up to the ridge
