!!!!!!!!!!!!!!!!HELP

Answer 1

Answer:

You have to use this equation: $a^{2} + b^{2} -c^{2}$

Step-by-step explanation:

C is the hypotenuse but you need another one  so you got to do

$x^{2} +8^{2} =17^{2}$

now you have to find $x^{2}$ which is

$x^{2} = 17^{2} - 8^{2}$

$x^{2} = 289 - 64$

$x^{2} = 225$

$x = \sqrt{255}$

$x = 15$
