Question

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

Explanation:

Step1: Apply Pythagorean theorem

$$c^2 = a^2 + b^2$$

Step2: Substitute given values

$$c^2 = 4^2 + 5^2 = 16 + 25 = 41$$

Step3: Solve for c

$$c = \sqrt{41} \approx 6.4$$

Answer:

6.4 miles
