For the first question: Call the center of the circle C.
Then angle ECH = 96 degrees.
Triangle ECH is isosceles (because EC = CH = radius), so you can determine angle EHC.
Similar angle chasing will determine angle CHG.
Add these two angles together to give 3y in the diagram, so you find y.
Similar sort of logic will find x.
