Answer:
the whole circle is 360⁰
/ to get the angle of. inscribed angle u need to divide the intercepted angle to 2
like in no.1 mABC (INTERCEPTED ARC) =120⁰ DIVIDED BY 2 =60
/to get the the another arc just subtract the intercepted arc into 360⁰ or vice versa.
mABC (INTERCEPTED ARC) =120⁰ MINUS 360 = 240⁰
/ in number 5 ay central angle, may angle na ang vertex ay sa center ..ang central angle is congruent to the intercepted arc
kaya mbc na intercepted ay 54 , mboc ay 54⁰ din
the same with no.6 na ang central angle daw ay 132 so ang arc bc ay 132 din

not sure sa number 7
