Question

calcule o valor de x nos triângulos retângulos

Answer 1

$a) \\ {x }^{2} = m \times n \\ {x}^{2} = 9 \times 16 \\ x = \sqrt{144} \\ x = 12$
$b) \\ c \times b = h \times a \\ 20x = 12 \times 25 \\ 20x = 300 \\ x = 300 \div 20 \\ x = 15$
$c) \\ {c}^{2} = m \times a \\ {3}^{2} = 5x \\ 9 = 5x \\ x = 9 \div 5 \\ x = 1.8$
