RSA Decryption?


I am playing a game in my university where you have different puzzles based on cryptography and now into a file name ‘rsa’, we have 2 files: ‘key’, ‘secret’. The task for this is to decrypt the secret message using the key, and ofcourse I am suspecting some RSA encryption but I can’t find anything to decrypt this and I think I might have too little informations.. I don’t really know. anyway, Here is the key:

UPDATE: No, I’m not sure, don’t think that the message is encoded in hexa too.

found out that RSA KEY was actually coded in hexa and the RSA key is basically:
