Answer:
The answer is 9in.
Explanation:
To solve this problem, you must use the Pythagorean Theorem.
Since we already have the Hypotenuse (
), which is 15in, we must solve the following:
+
=
Now, we find that
= 225, so we subtract that from
, which is 114.
Then, that leaves us with 81, and the sqaure root of 81 is 9, which is your answer.
