What is the measure of BC?

Answer:
The measure of arc BC is 96 degrees
Step-by-step explanation:
we know that
The inscribed angle is half that of the arc it comprises.
so
[tex]m\angle BAC=\frac{1}{2}[arc\ BC][/tex]
we have
[tex]m\angle BAC=48^o[/tex]
substitute
[tex]48^o=\frac{1}{2}[arc\ BC][/tex]
[tex]arc\ BC=2(48^o)=96^o[/tex]
