Default Re: [High School - Physics]

Well, you may not be in high school, but you're having a problem with simple algebra, so surely you can understand the assumed level...

Collect all the T1s term on one side and then factor out T1. Then just divide from there. Recall that multiplication and division are associative, so you shouldn't have a problem isolating T1 and keeping the products of the two cosines and the two sines clean and separate from the other. Factoring out T1 just makes use of the distributive property.

You should be left with T1*(sine and cosine stuff) = mg

From there, just divide both sides by the stuff and you're good.
