Question

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

Explanation:

Step1: Apply Pythagorean theorem

$c^{2}=a^{2}+b^{2}$, where $a = 20$ and $b = 48$. So $c^{2}=20^{2}+48^{2}$.

Step2: Calculate squares

$20^{2}=400$ and $48^{2}=2304$. Then $c^{2}=400 + 2304=2704$.

Step3: Find square - root

$c=\sqrt{2704}=52$.

Answer:

52
