Answer 1

pls mark it as brainlist

Answer 2

If you increase the line DC, that it touch OA on the point E.

Then, ED || AB...........because CD || AB

Now, On point C =>

< OCE + 110° = 180°.....linear pair.

< OCE = 70°.........◆

Now, < OEC = < EAB......corresponding angles.

< OEC = 60°.......◆

Now, in the ∆ OEC =>

< OCE + < OEC + < EOC = 180°

70° + 60° + < AOC = 180°....<EOC = < AOC

< AOC = 180° - 130°

< AOC = 50°.............●●●●●
