I need help

Answer 1

24 = x

Explanation:

You use Pythagorean theorem. Since the normal equation is
`a^(2) + b^(2) =c^(2)`, you already have the
`c^(2)` and another side which can be
`a^(2)` or
`b^(2)`.

Because you have the hypotenuse and a side , your equation looks like this now:
`7^(2) +b^(2) = 25^(2)`

and when you solve for be you just subtract
`25^(2) -7^(2)` to get 24.
