Question

determine a medida da de cada um dos triângulos

Answer 1

TRIANGULO EQUILATERO
>>>>>>>>>>>>>>>>>>>>>>>>
Vamos a calcular com Teorema de Pitagoras :

(20)^2 = (10)^2 + x^2
400 = 100 + x^2
x^2 + 100 = 400
x^2 = 400 - 100
x^2 = 300
x = \/300
x = \/100.3
x = 10.\/3

TRIANGULO ISOSCELES
>>>>>>>>>>>>>>>>>>>>>>
Vamos a calcular com Teorema de Pitagoras :

(25)^2 = (15)^2 + x^2
625 = 225 + x^2
x^2 + 225 = 625
x^2 = 625 - 225
x^2 = 400
x = \/400
x = \/20.20
x = 20
