what is the length of the missing leg? if necessary, round to the nearest tenth. b = miles
Answer
Answer:
$2.2$
Explanation:
Step1: Apply Pythagorean theorem
$a^{2}+b^{2}=c^{2}$, where $c = 3$ (hypotenuse) and $a = 2$ (one - leg), we want to find $b$. So $b=\sqrt{c^{2}-a^{2}}$.
Step2: Substitute values
$b=\sqrt{3^{2}-2^{2}}=\sqrt{9 - 4}=\sqrt{5}$.
Step3: Calculate and round
$\sqrt{5}\approx2.236\approx2.2$ (rounded to the nearest tenth).
