Question

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

Explanation:

Step1: Apply Pythagorean theorem

$$c^2 = 36^2 + 77^2$$

Step2: Calculate squared side lengths

$$c^2 = 1296 + 5929$$

Step3: Sum the squared values

$$c^2 = 7225$$

Step4: Take square root of sum

$$c = \sqrt{7225}$$

Answer:

85 kilometers
