The Attempt at a Solution



I'm attempting to solve a question with a few unknowns, and I managed to get it to the following form:

tanx(1-cosx)=0.25


I just cant seem to simplify it further and thus solve.. Any ideas?

It is more helpful if you post the entire original question and your work so far; otherwise we can't tell whether you've made a mistake in the work leading up to this point, or indeed whether you're expected to find an exact or merely approximate solution.

Ok.
Find theta.
2sintheta(75)(x-1.2)=45, where x=1.2costheta
