Answer:
Explanation:
The Pythagorean Theorem states that:
where
and
are legs of a right triangle (they meet at the right angle), and
is the triangle's hypotenuse.
We can apply this theorem to the given triangle:
,
and all we have to do is solve for x.
First, simplify all the square roots.
Then, subtract 64 from both sides.
Finally, take the square root of both sides.
