Solve the formula for the given letter. Assume all variables represent nonnegative numbers.

a^2+k^2=j^2, solving for a

a^2+k^2=j^2

a^2 = j^2 - k^2
a = square root ( j^2 - k^2 )

To solve the formula a^2 + k^2 = j^2 for the variable a, we need to isolate a on one side of the equation. Here's how you do it:

1. Start with the given equation: a^2 + k^2 = j^2.

2. Subtract k^2 from both sides of the equation to isolate a^2: a^2 = j^2 - k^2.

3. Take the square root of both sides to solve for a: √(a^2) = √(j^2 - k^2).

4. Simplify the equation: a = √(j^2 - k^2).

Therefore, the solution to the formula for a is a = √(j^2 - k^2).
