Los puntos (1,-2);(-8,4 y (5,2) son los vertices de un triangulo rectángulo su perimetro es aproximadamente

Alenkasestr [34]

Answer:

El perímetro del triángulo rectángulo es aproximadamente 29.627.

Step-by-step explanation:

Las coordendas de los vértices del triángulo rectángulo son $A(x,y) = (1,-2)$ , $B(x,y) = (-8,4)$ y $C(x,y) = (5,2)$ . En primer lugar, determinamos las longitudes de los segmentos AB, BC y AC por el Teorema de Pitágoras:

$AB = \sqrt{(-8-1)^{2}+[4-(-2)]^{2}}$

$AB \approx 10.817$

$BC = \sqrt{[5-(-8)]^{2}+(2-4)^{2}}$

$BC \approx 13.153$

$AC =\sqrt{(5-1)^{2}+[2-(-2)]^{2}}$

$AC \approx 5.657$

El perímetro del triángulo ( $p$ ) es la suma de todos estos segmentos:

$p = AB + BC + AC$

$p \approx 29.627$

El perímetro del triángulo rectángulo es aproximadamente 29.627.
