Question

Calcule o valor de x nos triângulos. (10 pontos)

Answer 1

A) x² = (√2)² + (√3)²
x² = 2 + 3
x² = 5
X = √5

B) (3√5)² = x² + 6²
9 • 5 = x² + 36
45 = x² + 36
x² + 36 = 45
x² = 45 - 36
x² = 9
x = √9
x = 3

Answer 2

A) x² = (√2)² + (√3)²

x² = 2 + 3

x² = 5  

X = √5

B) (3√5)² = x² + 6²

9 • 5 = x² + 36

45 = x² + 36

x² + 36 = 45

x² = 45 - 36

x² = 9

x = √9

x = 3
