Question

A, B, C are any points on the circle with centre
O. If m arc (BC) = 110° and m arc (AB) =
125°, find measure arc AC

Answer 1

BC is 110° AB is 125° and AC is -360 answer

Answer 2

Answer:

complete circle measure=360

m(arc BC)= 125

m(arc AB) =110

A,B,C

arc BC+ arc AC +arc AB =360

125+arc Ac+110=360

arc AC =360-125-110

arc AC =175-110

arc AC =65

m(arc AC ) =65
