Answer:
The answer is 9in.
Step-by-step explanation:
To solve this problem, you must use the Pythagorean Theorem.
Since we already have the Hypotenuse ([tex]c^{2}[/tex]), which is 15in, we must solve the following:
[tex]12^{2}[/tex] + [tex]b^{2}[/tex] = [tex]15^{2}[/tex]
Now, we find that [tex]15^{2}[/tex] = 225, so we subtract that from [tex]12^{2}[/tex], which is 114.
Then, that leaves us with 81, and the sqaure root of 81 is 9, which is your answer.
