Question

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

Explanation:

Step1: Apply Pythagorean theorem

$c^2 = a^2 + b^2$ where $a=4.9$, $b=2.4$

Step2: Calculate squared side lengths

$c^2 = 4.9^2 + 2.4^2 = 24.01 + 5.76$

Step3: Sum the squared values

$c^2 = 29.77$

Step4: Take square root, round to tenth

$c = \sqrt{29.77} \approx 5.5$

Answer:

5.5 centimeters
