PLEASE HELP! I HAVE A CHAPTER TEST TM ON THIS

Directions: Solve the right triangle. Round decimal answers to the nearest tenth.

OKK so my question is I’m not sure what to do with the sqaure root. It throws me off, like I understand how to do this but the square root is confusing me. Can someone do the problem for me and explain your steps? It would help me a ton!
