Question

Solve c2=a2+b2 for b

Answer 1

Answer:

A^2+B^2=C^2

B^2=C^2-A^2

B=SQRT(C^2-A^2

Step-by-step explanation:

Answer 2

Answer:

$b=\sqrt{c^2-a^2}$.

Step-by-step 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;

$\pm \sqrt{c^2-a^2}=b$.

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

$b=\sqrt{c^2-a^2}$.
