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 ?
substitute the values
a+b+c = 180
48+59+b=180
107+b=180
b=180-107
b=73
0.8
80p= 80/100
8/10
4/5
