Question

what is the length of the missing leg? if necessary, round to the nearest tenth. b = \boxed{} meters

Explanation:

Step1: Apply Pythagorean theorem

$a^2 + b^2 = c^2$ where $a=4$, $c=7$
$4^2 + b^2 = 7^2$
$16 + b^2 = 49$

Step2: Solve for $b^2$

$b^2 = 49 - 16 = 33$

Step3: Calculate $b$

$b = \sqrt{33} \approx 5.7$

Answer:

5.7
