Here are a couple of my homework problems that I need some help with. I don't know where to even start. Would someone please be kind enough as to help?
Problem 1. http://i42.tinypic.com/2ikusjn.jpg
I need to find measures of angles
I was also suppose to find measure of arc AD and I found it to be 56, is that correct?
Problem 2. http://i43.tinypic.com/1fu0xi.jpg
Solve for x and y.
I found x = 50 but i have no idea where to start with y.
Problem 3. http://i44.tinypic.com/34zbubm.jpg
Solve 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.
