Question

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

Explanation:

Step1: Apply Pythagorean theorem

$a = 2.6$, $b = 4.9$, and the Pythagorean theorem is $c^{2}=a^{2}+b^{2}$. So $c^{2}=2.6^{2}+4.9^{2}$.

Step2: Calculate squares

$2.6^{2}=6.76$ and $4.9^{2}=24.01$. Then $c^{2}=6.76 + 24.01=30.77$.

Step3: Find c

$c=\sqrt{30.77}\approx5.5$

Answer:

$5.5$
