Question

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

Answer 1

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! :)
