Answer:


b=√(c^2-a^2).

Explanation:

The given expression is
c^2=a^2+b^2.

We want to solve this equation for
b , we subtract
a^2 from both sides of the equation.


c^2-a^2=b^2.

We take the square root of both sides to get;


\pm √(c^2-a^2)=b.

Note however that; if b represents one of the legs of a right triangle or any non negative quantity, then


b=√(c^2-a^2).
