Can anyone explain point 44 of the attached pdf document on surface tension.

(Here's the link in case attachment doesn't work:

How is the surface tension direction found out?
Also why is surface tension for Solid-Air Surface considered when balancing forces on liquid?
Any help will be appreciated
Thank you.

direction will be tangential to both interfaces.
