Answer:

Angle AOC = 35°
Angle COF= 105°

Step-by-step explanation:

Angle AOE = Angle FOB = 40° [Vertically opposite angles]

Angle BOD = Angle AOC = 35° [Vertically opposite angles]

Angle AOC + Angle COF +  Angle FOB = 180°
40° + Angle COF + 35° = 180°
Angle COF + 75° = 180°

Angle COF = 180 - 75 = 105°

Answer:

angle AOC=35°

angle COF=105°

Step-by-step explanation:

Step-by-step explanation:angle AOE+EOD +DOB=180°. (LINEAR PAIR)

. (LINEAR PAIR) 40+EOD+35=180°

EOD=180°-75°

EOD= 105°

angle EOD=angle COF (vertically opposite angles)

angle COF=105°

angle AOC= angle DOB

angle AOC=35°
