Answer:  30°      9'      50"

Step-by-step explanation:

you need to borrow from the Minutes column to be able to subtract the Seconds column. Reminder that 1 minute = 60 seconds.

    60°     50'     40"     ⇒      60°     49'     100"

-   30°     40'     50"         -    30°     40'     50"  

                                               30°      9'      50"
