For the two circles x is equal to the radius, for the first circle we have x = 9 units and for the second one we have x = 11 units.
<h3>
How to find the length of the segments?</h3>
Define how circles are defined. A circle is the set of all points on a plane that is equidistant to a given point, which we call the center of the circle.
That constant distance is called the radius, so the distance between the center of the circle and any point on the circumference is constant.
Now, let's look at the first circle, here you can see that the lenght "x" connects the center with the circumference, this, x is equal to the radius. And the other segment also does that and it measures 9 units, then we can conclude:
x = 9
For the other triangle we have exactly the same situation, here x also represents the radius, and this time we can see that the radius measures 11 units, then:
x = 11 units.
