Answer 2

Solution!!

Given:-

∠AOC = 70°

∠BOD = 50°

To find:-

∠COD

The angles are being formed on a straight line. If the angles are formed on a straight line then the sum of those angles is equal to 180°. So, we will add the angles and get the value of ∠COD.

∠AOC + ∠BOD + ∠COD = 180°

70° + 50° + ∠COD = 180°

120° + ∠COD = 180°

∠COD = 180° - 120°

∠COD = 60°

(B) 60° ✔️

More about angles:-

Vertical angles → The angles opposite of each other at the intersection of two lines sharing a common vertex.

Corresponding angles → The pair of angles on same side of transversal and on the corresponding corners when two parallel lines are intersected by any other line.
