I'm only looking for help and not answers-- thanks!
The side lengths of a cyclic quadrilateral ABCD are provided in the diagram. Find BD^2.
The picture is here as I can't upload it for some reason: https://cutt.ly/auSLG9T
How do I start? I've tried to find the product of the two diagonals and work backwards from there but that didn't work.
This class is about Trig, so perhaps that's the way? I can't figure out how to solve it using that, however.
Thank you!
