a = yards
submit

Explanation:

Step1: Apply Pythagorean theorem

For a right triangle, $c^2 = a^2 + b^2$, where $c=15$, $b=9$. Rearrange to solve for $a$:
$a^2 = c^2 - b^2$

Step2: Substitute known values

$a^2 = 15^2 - 9^2 = 225 - 81$

Step3: Calculate the difference

$a^2 = 144$

Step4: Take square root of result

$a = \sqrt{144}$

Answer:

12 yards
