Why is one that's one squared plus x squared? Because our word, which is two squared, which is what? So we have four minutes one x squared, which means that X is equal to the square root of three. Okay, so this is clearly a defeat so that we can find a other angles. So we know that coastline of data. The people here, Jason over. Hi, Panis.
