ANSWER:

Given

AOB is a straight line

Then ∠AOB = 180°

Ray OC & Ray OD stands on line AOB

∠AOC = 65°

∠BOD = 70°

TO FIND

∠COD = x°

Here,

∠AOB = ∠AOC + ∠COD + ∠BOD

180° = 65° + 70° + x°

180° - 135° = x°

x° = 55°

Note: straight line = 180°

Because it has two right angles if we divide perpendicularly

And we know that right angle = 90°

2 right angles = 2(90°) = 180°
