somehow v. somewhat v. sort of

[hhtt]

In the sentence "You have sort of answered your own question." Are somehow, somewhat and sort of interchangeable and are they state adverbs?

Thank you.

You could use "somewhat" in the sentence without changing the meaning, though it would sound a little odd. Using "somehow" would change the meaning entirely.
