Answer:
A^2+B^2=C^2
B^2=C^2-A^2
B=SQRT(C^2-A^2
Step-by-step explanation:
Answer:
[tex]b=\sqrt{c^2-a^2}[/tex].
Step-by-step explanation:
The given expression is [tex]c^2=a^2+b^2[/tex].
We want to solve this equation for [tex]b[/tex] , we subtract [tex]a^2[/tex] from both sides of the equation.
[tex]c^2-a^2=b^2[/tex].
We take the square root of both sides to get;
[tex]\pm \sqrt{c^2-a^2}=b[/tex].
Note however that; if b represents one of the legs of a right triangle or any non negative quantity, then
[tex]b=\sqrt{c^2-a^2}[/tex].
