Question

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

Explanation:

Step1: Apply Pythagorean theorem

$c^{2}=40^{2}+42^{2}$

Step2: Calculate squares

$40^{2}=1600$, $42^{2} = 1764$, so $c^{2}=1600 + 1764=3364$

Step3: Find c

$c=\sqrt{3364}= 58$

Answer:

58
