Question

  1. determine whether the forces in the pair are pulling at right angles to each other.

for the values ( a = 2.9 ) which is a leg of a right triangle, and value ( c = 4.2 ), which is the hypotenuse, find the length of the other leg, ( b ), to the nearest tenth.
1.3
3.0
2.8
2.9

Explanation:

Step1: Aplicar el Teorema de Pitágoras

El Teorema de Pitágoras establece que \(a^{2}+b^{2}=c^{2}\), donde \(a\) y \(b\) son los catetos y \(c\) es la hipotenusa de un triángulo rectángulo. Dado \(a = 2.9\) y \(c=4.2\), despejamos \(b\): \(b=\sqrt{c^{2}-a^{2}}\).

Step2: Calcular \(c^{2}-a^{2}\)

\(c^{2}=(4.2)^{2}=17.64\) y \(a^{2}=(2.9)^{2}=8.41\). Entonces \(c^{2}-a^{2}=17.64 - 8.41=9.23\).

Step3: Calcular la raíz cuadrada

\(b=\sqrt{9.23}\approx3.0\) (redondeado a la décima más cercana).

Answer:

3.0
