solving for length of a bisected triangle side based on proportions?

[markhunter72]

Please see attached triangle problem. The instructions say to solve using proportions but I'm not sure how to do this since the triangles formed are not similar. How an this problem and length x be solved for using proportions and not the law of sines and cosines?

Thank you!

solution using law of cosines and sines

I can solve for x as 2.1, using the law of cosines and sines, but the instructions are to use proportions. I am still confused??

Thank you.
