Thank you for the explanation

Just going to point out a small mistake - The angle labeled 65 degrees should be 55 degrees

Thanks for bringing that to my attention-- you're right. The explanation in the video still basically works in terms of approach and methodology, but that 65 really should be a 55, since 125+55 = 180 degrees.
