1 answer:
Answer:
Part 1)
Part 2)
Step-by-step explanation:
Part 1) What is the measure of AC ?
we know that
The inscribed angle is half that of the arc it comprises.
so
substitute the values and solve for x
Find the measure of arc AC
Part 2) What is the measure of BC ?
we know that
The inscribed angle is half that of the arc it comprises.
so
