Question

What is the measure of BC?

Answer 1

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

$m\angle BAC=\frac{1}{2}[arc\ BC]$

we have

$m\angle BAC=48^o$

substitute

$48^o=\frac{1}{2}[arc\ BC]$

$arc\ BC=2(48^o)=96^o$
