Would someone please be kind enough as to help?Problem 1. http://i43.tinypic.com/1fu0xi.jpgSolve for x and y. I found x = 50 but i have no idea where to start with y.Problem 2. http://i44.tinypic.com/34zbubm.jpgSolve for z.I guess my biggest problem is i don't know the relation between the different inscribed angles. Any help would be greatly appreciated! Thank you very much in advance
