Question

Determine o valor de x em cada triângulo:
​

Answer 1

Resposta:

a) x²=3²+4²

x²=9+16

x=√25=5

b) 13²=5²+x²

169=25+x²

x²=169-25

x=√144=12

c)7,5²=4,5²+x²

56,25=20,25+x²

x²=56,25-20,25

x=√36=6

Answer 2

Resposta:a)5. b)12 c)6

Explicação passo-a-passo:

a) x^2=3^2 +4^2

x^2=9+16

x=√25

x=5

b)13^2=5^2+x^2

x^2=13^2-5^2

x^2=169-25

x^2=144

x=√144

x=12

c)(7,5)^2=(4,5)^2+x^2

56,25=20,25+x^2

x^2=56,25-20,25

x^2=36

x=√36

x=6
