Step-by-step explanation:
[tex]x = \frac{1}{2} \times 70 \degree = 35 \degree \\ \\ reason: \angle \: on \: circle \: is \: half \: to \: \\ the \: angle \: on \: center \: of \: circle \\ \\ y \: + 70\degree = 180\degree \\ ..(opposite \: \angle \: s \: of \: cyclic \: quadrilateral) \\ y = 180\degree - 70\degree \\ \\ y = 110\degree [/tex]
