Question
(geometry, unit 4, lesson 3)
find the length of each leg.
type the answers in the boxes below.
pq =
units
qr =
units
Step1: Identificar el triángulo
Se trata de un triángulo rectángulo de 30-60-90, con hipotenusa $PR = 4$.
Step2: Calcular el cateto corto (PQ)
El cateto opuesto al ángulo de 30° es la mitad de la hipotenusa.
$PQ = \frac{1}{2} \times PR = \frac{1}{2} \times 4 = 2$
Step3: Calcular el cateto largo (QR)
Usar el teorema de Pitágoras: $QR = \sqrt{PR^2 - PQ^2}$
$QR = \sqrt{4^2 - 2^2} = \sqrt{16 - 4} = \sqrt{12} = 2\sqrt{3}$
