Find the length of the third side. If necessary, write in simplistic radical form.

____ [38]

Answer:

7

Step-by-step explanation:

Just use the Pythagorean Theorem ( $a^{2}$ + $b^{2}$ = $c^{2}$ )

Let a be the missing side

$a^{2}$ = $8^{2}$ - $\sqrt{15} ^{2}$

$a^{2}$ = $64$ - $15$

$a^{2}$ = $49$

Take the square root of each side

$a$ = $\sqrt{49}$

$a$ = $7$

So the missing side is 7.

Hope this helps! :)
