please slove fast please​

Answer 1

Answer:

120 degrees

Step-by-step explanation:

because this is straight angle,angle aob is 60 degrees and boc is 180 degrees

Answer 2

Answer:

The value of $x=120$°.

Step-by-step explanation:

We have properties for angles, one of them are :

• The sum of angles on a straight line is $180$°.

Here AC is a straight line , O its midpoint, and ∠AOB, ∠COB are angles on it.

Moreover it is given that ∠AOB $=60$°.

We know by the property ∠AOB $+$ ∠COB $=180$°, We have to find ∠COB.

Therefore ∠COB $=180-$∠AOB

                            $=180-60=120$.

Hence  ∠COB  $=x=$$120$°.

Hence the answer
