We would use the Pythagorean theorem because we could create triangle by connecting the points L and J
We have 3.6 as a side, and to find the other we divide 8 by 2, so the side would be 4.
The line LJ is the hypotenuse, and also the radius
a^2+b^2=c^2
a= 3.6 b=4
3.6^2+4^2=c^2
12.96+16=c^2
28.96=c^2 *square root both sides*
c= 5.38= LJ
Since the radius of a circle is always the same, then LJ and X would be equal so…
X=5.38
