what is the length of the hypotenuse? if necessary, round to the nearest tenth.\nc = kilometers

Explanation:

Step1: Apply Pythagorean theorem

$$a^{2}+b^{2}=c^{2}$$ Here (a = 5), (b = 8). So (5^{2}+8^{2}=c^{2})

Step2: Calculate squares

(25 + 64=c^{2}) (c^{2}=89)

Step3: Find (c)

(c=\sqrt{89}\approx9.4)

Answer:

(9.4)
