Answer:
angle AOC = 77°
Step-by-step explanation:
angle COD = 55°(given)
=> angleAOC + angle COD + angle DOB = 180° (linear pair)
=> (3x-7)° + 55° + ( x+20)° = 180°
=> 4x + 68° = 180°
=> 4x = 180°–68°
=> 4x = 112°
=> x = 112°/4
=> x = 28°
Therefore,
angle AOC = (3x-7)°
= (3×28 -7)°
= (84-7)°
= 77°
angle DOB = (x+20)°
= (28+20)°
= 48°
hope it helps you :)
