Answer 1

y = 90°

Explanation:

By remote interior angle theorem:

`2x + 70 \degree = 110 \degree \\ \\ 2x = 110 \degree - 70 \degree \\ 2x = 40 \degree \\ \\ x = (40 \degree)/(2) \\ \\ x = 20 \degree \\ \\ again \: by \: remote \: interior \: \\angle \: theorem \\ \\ x + y = 110 \degree \\ \\ 20 \degree + y = 110 \degree \\ \\ y = 110 \degree - 20 \degree \\ \\ \huge \red{ \boxed{y = 90 \degree }}`
