Answer 2

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

So first you should remember that....

$a^{2} +b^{2} =c^{2}$

then you should plug in...

$8^{2}+16^{2}$

that should equal...

$c^{2}=320$

Then you should solve the equation now by doing the inverse of the square which is the square root of both sides...

$\sqrt{c^{2} } =\sqrt{320}$

$c=17.88854382...$

Then you have to round it to the nearest tenths, which'll give you...

$17.9$

choice D
