Answer 2

Answer:

90°+ angle AOC+30° =180°

120°+ angle AOC =180°

angle AOC = (180-120)°

angle AOC=60°

angle DOF =angle EOC =30° (Vertically opposite angles). (1)

angle AOF + angle DOF + angle BOD = 180°. ( linear pair)

90° + 30° + 3y = 180°

120°+3y =180°

3y=(180-120)°

3y= 60°

y=60/3

y= 20
