Here's a couple of construction lines. Hopefully, you should be able to do it now.
Hi
I'll give you some clues with this first post, more if you ask for it.. To be honest I had to give this some thought!
On my attachment, I've taken your diagram and added some bits.. I've named some of the points, just for convenience, and drawn to radiuses BC and CD.
Do you know the rule for the angle at the centre of the circle if you know the angle made by the cord on the circumference? If you don't, you may need another post from me.
Can you see what the angles are between AB and BC, and AD and CD?
What do the angles in ABCD add up to?
Does that help us find x?

thank you so much, this was really helpful!
a= 90, b = 90, y = 76, x = 104
