How do you solve the pythagorean theorem if you have 2 variables??
for instance: side a=10, side b=x-2 and side c=x.
-----
Formula: hypotenuse^2 = leg1 ^2 + leg 2 ^2
------
If you assume the hypotenuse = c = x you get the following:
----
x^2 = 10^2 + (x-2)^2
---
x^2 = 10^2 + x^2-4x+4
---
-4x + 104 = 0
-x + 26 = x = 26 (side c; the hypotenuse)
x-2 = 24 (side b)
