Question

what is the process of fermentation?​

Answer 1

Explanation:

Fermentation, chemical process by which molecules such as glucose are broken down anaerobically

Answer 2

Explanation:

We have :

∠AOC=∠BOD   [Vertically-Opposite Angles]∴∠AOC+∠BOD=130°⇒∠AOC+∠AOC=130°   [∵∠AOC=∠BOD]⇒2∠AOC=130°⇒∠AOC=65°

Now,

∠AOC+∠AOD=180°  [∵COD is a straight line] ⇒65°+∠AOD=180°⇒∠AOC=115°
