Answer 2

Answer:

∠COD= 60°

Step-by-step explanation:

Given:

∠AOB is a straight line

⇒∠AOB = 180°

⇒∠AOC + ∠COD + ∠BOD  = 180°

⇒(x + 20°) + (2x - 20°) + 60° = 180°

⇒3x + 60°=180°

⇒3x = 180°- 60°

⇒3x=120°

⇒x= 120°÷ 3

⇒x= 40°

To Find:

∠COD = ?

⇒ ∠COD= 2x - 20°

⇒ ∠COD= 2 × 40° - 20°

⇒ ∠COD= 80° - 20°

⇒  ∠COD= 60°
