if the sides are equal, and the angle is 90 degrees, you can rotate one triangle to get a rectangle

Where does the 100x come from? The other numbers - 900, 2,500 & 400 - are fairly obvious, if someone is watching the video they probably don't understand were the 100x came from; if they do they are probably not watching the video.

(50 - 𝑥)² = (50 - 𝑥)(50 - 𝑥) = 50*50 - 50𝑥 - 50𝑥 + (-𝑥)(-𝑥) = 2500 - 100𝑥 + 𝑥² (a - b)² = a² - 2ab + b² Thanks, I'll write out more details next time
