I want to find x for (1) and x and y for (2). I am not sure how to put the images directly into the thread so I apologize if you do not like having to click on them. On the first one, I do not know how we can find this without knowing that XW is a diameter (it is not given as one in the problem). On the second one I am guessing I must use some type of property of quadrilaterals? Any help will be greatly appreciated.
