Answer:

C;
x=√(17)

Explanation:

To find the missing length of a right triangle, we can use the Pythagorean Theorem. This theorem states that
a^(2)+b^(2)=c^2, where a and b are the legs of a right triangle and c is the hypotenuse. In our problem, we are solving for one of the legs. In this problem we'll say that a=8 and b=x while c=9. Now, let's solve for x.


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

a=8

b=x

c=9


8^2+x^2=9^2\\64+x^2=81\\x^2=17\\x=√(17)

So, our answer must be C.

If this answer helped you, please leave a thanks!

Have a GREAT day!!!
