Question

utilizando o teorema de Pitágoras,calcule o valor de x

Answer 1

A)
${a }^{2} = {b}^{2} + {c}^{2}$
${5}^{2} = {x}^{2} + {3}^{2}$
${5}^{2} = {3}^{2} + {x}^{2}$
$25 = 9 + {x}^{2}$
${x}^{2} = 25 + 9$
$x = \sqrt{34}$
$x = 5$

Answer 2

Explicação passo-a-passo:

A) 5²=3²+x²

25=9+x²

-x²=9-25

x=√16

x=4

b) x²=10²+20²

x²=100+400

x²=500

x=√500

x=2√145

c)5000²=3000²+x²

25000000=9000000+x²

-x²=9000000-25000000

x=√-16000000

x=4000

d)12²=x²+8²

144=x²+64

-x²=64-144

x=√80

x=4√5
