Answer:
The measure of arc AC length is 90 degrees
Step-by-step explanation:
Here, we want to get the measure of the arc AC
From what we have, the angle at the middle facing this arc is a right angle
A right angle is of the size 90. degrees
with respect to the diagram, the angle at the center is equal to the measure of the arc facing it
Thus, we can conclude here in this case that the measure of arc AC is 90 degrees
