Question

aob is straight line then cod is equal to​

Answer 1

Answer:

60°

Step-by-step explanation:

AOB is a straight line

∴∠AOC+∠COD+∠DOB=180

∘

⇒x+20

∘

+2x−20

∘

+60

∘

=180

∘

⇒3x=120

∘

⇒x=40

∘

∠COD=2x−20

∘

=(2×40

∘

)−20

∘

=60

∘

Answer 2

Answer:

AOB is a straight line,

therefore,angle AOC + angle COD + ankle DOB =180°

=x+20°+2x-20°+60°=180°

=3x=120°

x=40°

angle COD=2x-20°

=(2×40)-20°

=60°
