This is a lovely question that I was emailed by brilliant.org If you haven't seen that site then do go there. I suggest signing up for the free access and having fun exploring some of their frankly brilliant problems. This one involves some nice techniques and will allow you to delve into different A-level maths ideas.
im normally not good at geometry but can i post my solution???? (im proud of myself for it lol)
