In the formula a2+b2=c2, what is the value of a2?

A^2 + b^2 = c^2this is the pythagoream theroum (sorry, probably spelled it wrong)it is used for right triangles.
a and b are ur legs of the triangle and c is the hypotenuse. Therefore, the value of a^2 is the value of one of the legs, squared.
OR. if u mean this..
a^2 + b^2 = c^2
a^2 = c^2 - b^2

The answer is A
