Question

question find the length of the third side. if necessary, round to the nearest tenth. answer attempt 2 out of 2 submit answer

Explanation:

Step1: Identify Pythagorean theorem

For right triangle: $a^2 + b^2 = c^2$, where $c=5$ (hypotenuse), $a=3$, $b$ is unknown side.

Step2: Rearrange to solve for $b$

$b = \sqrt{c^2 - a^2}$

Step3: Substitute values and calculate

$b = \sqrt{5^2 - 3^2} = \sqrt{25 - 9} = \sqrt{16} = 4$
