Answer 1

now can u mark me as brainliest. If not then also well and if yes then also well. good day.

Answer 2

$= > x + 110 = 180 \: \: \: \: \: \: (linear \: pair) \\ = > x = 180 - 110 \\ = > x = 70 \\ \\ \\ now \: angle \: sum \: property \: of \: triangle \\ \\ = > y + x + 30 = 180 \\ = > y + 70 + 30 = 180 \\ = > y + 100 = 180 \\ = > y = 180 - 100 \\ = > y = 80$
