Question

1-Calcule o valor de x

Answer 1

Resposta passo a passo:

h² = a² + b²

a) a = 24 , b = 7 , h = x

x² = 24² + 7²

x² = 576 + 49

x² = 625

x = √625

x = √25²

x = 25

b) a = 12 , b = 5 , h = x

x² = 12² + 5²

x² = 144 + 25

x² = 169

x = √169

x = √13²

x = 13

c) a = 12 , b = x , h = 15

15² = 12² + x²

15² - 12² = x²

x² = 225 - 144

x² = 81

x = √81

x = √9²

x = 9

d) a = x , b = x , h = 10√2

(10√2)² = x² + x²

10²(√2)² = 2x²

100 . 2 = 2x²

100 = x²

x = √100

x = √10²

x = 10
