Question

what is the length of the hypotenuse? if necessary, round to the nearest tenth.
c = 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:

\(9.4\)
