Question

AOB is a straight line,if AOC +BOD =85°, find COD​

Answer 1

∠COD = 95°

Step-by-step explanation:

Given that,

∠AOC, ∠BOD, & ∠COD are three angles on a straight line

∠AOC + ∠BOD = 85°

To find,

∠COD = ?

Procedure:

∠AOC + ∠BOD + ∠COD = 180°                  (∵ Linear Pair)

By putting the value of (∠AOC + ∠BOD = 85°), we get

85° + ∠COD = 180°

∠COD = 180° - 85°

∵ ∠COD = 95°

Thus, 95° is the value of ∠COD.
