Question

Find the length of the hypotenuse round to the nearest hundredth

Answer 1

Answer:

$\displaystyle 4\sqrt{5}$

Step-by-step explanation:

Use the Pythagorean Theorem:

$\displaystyle a^2 + b^2 = c^2 \\ \\ 8^2 + 4^2 = c^2; \sqrt{80} = \sqrt{c^2} \\ \\ 4\sqrt{5}\:[or\:8,94427191...] = b$

So, you have this:

$\displaystyle 8,94 ≈ c$
