How do you find side a to a right triangle using pythagorean theorem?

a^2 = c^2 - b^2

Step-by-step explanation:

With the pythagorean therom you have a^2 + b^2 = c^2

Therefore a^2 = c^2 - b^2 you get this by subtracting b^2 from both sides

Once you have all the numbers you can just get the square root of them and youll have what a is
