Help with G-Code Arc & Radius

Hi everyone
Currently I am programming Mazak machines
but I was assigned a new machine.
Where I use G-codes
I have a problem with rays, arcs.
I made the first example myself using g2 / g3 / R

Attachment 29624

In the second example, I am supposed to use I, J
I am looking for some materials but they are hard to understand for me.

Does anyone have any material on using I, J for arcs and radius

Attachment 29625

Please write some code for this drawing
Use the I, J functions maybe then on this example I can understand how the commands work

Regards,
