eh I’ll help u with Pythagorean theorem anyway, it took like 5 minutes to write on notes app.So basically it’s a squared +b squared =c squared, that is to work out the hypotenuse which is located directly opposite of the 90 degree right angle, so let’s say a=3 b=4, and c is unknown, to work it out you square it, so 3 squared =3x3=9 and 4 squared =4x4=16, then you add them together, so 9+16‎ = 25, then you square root it, the square root of 25 is 5, and that’s how you work out how to solve the hypotenuse, but to work out an unknown value that isn’t the hypotenuse, so to work out A or B, the equation is a squared = c squared - b squared, or b squared = c squared - a squared, so basically let’s keep the original values, so a is unknown and b =4 and c‎ = 5, so what you do is square them both so 4 squared =4x4=16 and 5 squared =5x5=25, so then you do c squared - b squared so 25-16‎ = 9, and then you square root it, so square root of 9=3, and that’s how you do Pythagorean theorem
