what is the length of the missing leg? if necessary, round to the nearest tenth. a = miles

Answer

Explanation:

Step1: Aplicar el teorema de Pitágoras

Para un triángulo rectángulo con hipotenusa $c$ y catetos $a$ y $b$, $c^{2}=a^{2}+b^{2}$. Aquí $c = 2.4$ y $b = 1.9$, y queremos encontrar $a$. Re - arreglamos la fórmula: $a=\sqrt{c^{2}-b^{2}}$.

Step2: Sustituir valores

Sustituimos $c = 2.4$ y $b = 1.9$ en la fórmula: $a=\sqrt{(2.4)^{2}-(1.9)^{2}}=\sqrt{5.76 - 3.61}=\sqrt{2.15}$.

Step3: Calcular y redondear

Calculamos $\sqrt{2.15}\approx1.5$.

Answer:

$1.5$
