老师，我今天考试碰到的寂静题，一模一样！然后根本算不出来啊，两个式子结合是30x=5y.不知道寂静答案是怎么算出来x=15 y=90的？

请May老师解答～ 老师，您回复我的这一题，关于圆心角 和 圆周角，我有几个问题想问： 1. ABC是一个优弧，优弧的圆心角是怎么看的呢？为什么是∠BOC，而不是∠AOC呢？ 2. 此图中，（优弧）弧ABC 和 （劣弧） 弧AC是否有同一个圆心角 和 同一个圆周角呢？ 如果不是，老师可否分别把此图中 优弧与劣弧的圆心角和圆周角画一下？ 2. 优弧ABC所对应的圆周角 是∠E（我用红笔加上去的那一个）吗？

请May老师解答，想问一下鸡精的答案是不是错了？我的解答过程有没有问题？
