I have a question about visual binaries on a homework, which is at the link below.

http://pages.infinit.net/bdufou1/question2.jpg [Broken]

In addition to what is written in the question, we know that the sum of both masses is 3.3 times the mass of the sun, and Luminosity of A is three times that of the sun. I don't have any problem finding the radius of both stars, but i have no clue how to find the mass of each. I'm pretty sure the period is involved, but how??

Can somebody help??

Thanks in advance
