Question

NEED HELP ASAP algebra 2​

Answer 1

`8√(2)`

Explanation:

Step 1: Use Pythagorean Theorem to find the length of the hypotenuse

`a^(2)+b^(2) =c^(2)`

`9^(2)+7^(2) =c^(2)`

`81+47 =c^(2)`

`128 =c^(2)`

`\sqrt{c^(2) } =√(128)`

`c=√(128)`
`√(128) =8√(2)`

Therefore the third side is
`8√(2)`
