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

Answer:

5.5

Explanation:

Step1: Recall Pythagorean theorem

$a^{2}+b^{2}=c^{2}$, where $a = 2.6$, $b = 4.9$

Step2: Substitute values

$c=\sqrt{2.6^{2}+4.9^{2}}=\sqrt{6.76 + 24.01}=\sqrt{30.77}$

Step3: Calculate and round

$c\approx5.5$
