16
18
answer attempt 1 out of 2

Explanation:

Step1: Recall Pythagorean theorem

For right triangle: $a^2 + b^2 = c^2$, where $c=18$ (hypotenuse), $a=16$, $b$ is unknown side.

Step2: Rearrange to solve for $b$

$b^2 = c^2 - a^2$

Step3: Substitute given values

$b^2 = 18^2 - 16^2 = 324 - 256 = 68$

Step4: Calculate square root

$b = \sqrt{68} \approx 8.2$

Answer:

8.2
