Question

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

Explanation:

Step1: Apply Pythagorean theorem

$c^{2}=a^{2}+b^{2}$, where $a = 57$ and $b=76$. So $c^{2}=57^{2}+76^{2}$.

Step2: Calculate squares

$57^{2}=57\times57 = 3249$, $76^{2}=76\times76=5776$. Then $c^{2}=3249 + 5776=9025$.

Step3: Find square - root

$c=\sqrt{9025}=95$

Answer:

95
