Answer 2

Answer:

60

Step-by-step explanation:

You have the proper formula. You just need to swap some things around so we aren't solving for C. C is always the hypotenuse, the diagonal line opposite the right triangle. A and B can be either side unless specified.

1. The side we're solving for can either be called a or b. Let's call it A.

2. Now, switch around the theorem to solve for a: $C^2-B^2=A^2$

3. Plug in what we know: $8^2-2^2=a^2$

4. It simplifies down to $60=a^2$

5. The  "$a^2$ " means to square the a. We need to undo that to get a by itself. The opposite of squared is the square root

6. This leaves us to take the square root of both sides, which isolates a.

7. $\sqrt{60}$ is the answer. It's asking for it in the square root so we don't need to simplify it.
