Nice teaching

Hey Professor at 4:59. Apply the geometry rule angles inside a paralellogram = 360. Inside the parallelogram (lower corner & top corner) = 105.1° and thus 2(105.1°) + 2(X°) = 360. Angle X = 74.9°. Right? So, that angle 74.9° is the angle opposite of Fr. Now use the law of cosines. Done. Now, use that same method at 11:52. 2(10.63°) + 2(gamma) = 360 → gamma = 169.37 degrees. Done. It took you a minute and a half to get that.

what is the white digital board that you are using ??
