First, we need to find the due date of job A by adding 10 days to its release date (day 130 + 10 = day 140). Since it is now day 140, job A needs to be completed today or before to avoid any lateness. 
Using the longest processing time rule, job A will be the first to start processing since it has the longest processing time of 20 days. Therefore, it will be completed on day 160, which means it will not be late. The lateness of job A is 0.0 days.
