Basic Tigonometry - Advise Please

[Mothman]

I watched the basic tutorial here:
https://www.khanacademy.org/math/tr...ometry/basic_trig_ratios/v/basic-trigonometry

Where do I find the followup tutorial that discusses angles greater than 90 degrees ?
It was mentioned at the end of the basic tutorial linked above..

Thanks In Advance
