Could you borrow some of what you learned from the previous problem to solve this one?  You're not really starting from scratch.

Share any work you have done, please.

okay im not going to just tell you the answer but just think ac is equal to bc so what you need to do is use the equation bd + dc = ac then fill in the info you know to the equation. bd+4.1=6.8. now that should help you solve it is not just ask for more help and ill ecplain the final step
