What is the value of a in the formula, a² + b2 = c?

the length of a leg

Step-by-step explanation:

I think you mean the Pythagorean theorem a^2 + b^2 = c^2?

If so, it is describing the relation of a right triangle.

a and b are the legs(doesn't matter which is which) and c is the hypotenuse

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
