Why is the top right part of my MacBook making noises?

Hi guys!

Today, my brother dropped my computer and ever since then, every time I bend/ move the computer, the top right of the body of the computer (the base, where the keyboard is at), makes several cracking noises. I checked out the hinges, and It looks like the left hinge is a little bit bent (the first picture attached), with the hinge being more open as it looks like. How can I fix this issue?

Can you take the covers off so we can see things more clearly. Take a few pics from different angles so we have a better idea on were its damaged.
