Answer:
AC = 41
Explanation:
Inscribed Angle = 1/2 Intercepted Arc
4x-3.5 = 1/2 ( 4x+17)
4x-3.5 = 2x+8.5
Subtract 2x from each side.
4x-2x-3.5 = 2x-2x+8.5
2x -3.5=8.5
Add 3.5 to each side.
2x-3.5+3.5 = 8.5+3.5
2x = 12
Divide by 2.
2x/2 = 12/2
x=6
Now we can find the measure of AC
AC = 4x+17
=4*6+17
=24+17
=41
