Question

what is the length of the hypotenuse? if necessary, round to the nearest tenth.
c = \boxed{} miles

Explanation:

Step1: Apply Pythagorean theorem

For a right triangle, $c^2 = a^2 + b^2$, where $a=4$, $b=2$.
$c^2 = 4^2 + 2^2$

Step2: Calculate squared values

$c^2 = 16 + 4 = 20$

Step3: Solve for c

$c = \sqrt{20} \approx 4.5$

Answer:

4.5 miles
