Question

what is the length of the hypotenuse? if necessary, round to the nearest tenth. c = kilometers

Explanation:

Step1: Apply Pythagorean theorem

$a^{2}+b^{2}=c^{2}$, where $a = 5$, $b = 8$.

Step2: Calculate $c^{2}$

$c^{2}=5^{2}+8^{2}=25 + 64=89$

Step3: Find $c$

$c=\sqrt{89}\approx 9.4$

Answer:

$9.4$
