Hello, I am not sure how to do this question. Can you please help?

Use:

\(\displaystyle \frac{BC}{EC} \ = \frac{AC}{DC} \ = \frac{AB}{ED}\)........ and,,,,,,,,\(\displaystyle \frac{AB}{BF} \ = \frac{BC}{BE} \ = \frac{AC}{FE}\)

Please show us what you have tried and exactly where you are stuck.

I really do not know how to even start. I know it’s going to have something to do with ratio and proportion and probably not laws of Sine and Cosine, but I feel very lost. I will try to look at what you’ve written here.

I don’t know how to connect the area of the parallelogram to the ratio and proportion

I have written work down in the second picture that I uploaded. As you can see, I have two many variables and not enough equations. I think I am going in the wrong direction.
