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

Explanation:

Step1: Apply Pythagorean theorem

$$c^2 = 9^2 + 12^2$$

Step2: Calculate squared side lengths

$$c^2 = 81 + 144$$

Step3: Sum the squared values

$$c^2 = 225$$

Step4: Take square root of sum

$$c = \sqrt{225}$$

Answer:

15 yards
