Express 335°25’ as function of possitive acute angle?

Answer 1

Once around a circle is 360 deg.
Twice around is 2*360=720 deg

From any point in a circle you can add 360 and you'll get back to the same point. Likewise, you can subtract 360 and get back to the same point.

Now, about you problem: what is it you're asking for? Clearly 335 is almost all the way around. Acute means less than 90 deg. Which brings us back to the question: what is it that you're asking?

That's why you haven't gotten any answers: people don't know what your question means.
