Mr. Khan, I thank you from the bottom of my heart. I hope this becomes and evolves in the revolution Mr. Gates said it to be.

if CB is a transversal of the two parallel lines, I don't understand why you wouldn't get the correct value for x if you solved for it using the property which states that the two angles of any pair of consecutive interior angles of a transversal are supplementary. i.e. by solving the equation: 2x + (x+10) = 180 for x I understand what you demonstrated in the video and why it works, my question is how come the property that I mentioned above isn't consistent with the method you used? Algebraically I see why, but theoretically I have gotten myself very confused. I hope my question makes sense! And thank you! All of your videos have really helped me
