Question

in a circle with centre O , angle ABC = 30 degree , then find m ( arc APC ) and m ( arc AQC ) ​

Answer 1

Answer:

Step-by-step explanation:

In a circle angle subtended by any chord on opposite sides are supplementary.

So m(arcAPC)+m(arcABC)=180  

o

 

So m(arcABC)=180  

o

−60  

o

=120  

o
