Question

Teorema de Pitágoras

Answer 1

Resposta:

7)

AB^2=15^2+20^2

AB^2=225+400

$ab = \sqrt{625} \\ ab = 25 \: metros$

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

x^2=16+9

x^2=25

$x = \sqrt{25} \\ x = 5 \: metros$

8) x^2+7^2=13^2

x^2=49=169

x^2=169-49

x^2=120

$x = \sqrt{4 \times 30} \\ x = 2 \sqrt{30} \: \: milhas$

Bons Estudos!

Answer 2

Explicação passo-a-passo:

7)

$\sf h^2=15^2+20^2$

$\sf h^2=225+400$

$\sf h^2=625$

$\sf h=\sqrt{625}$

$\sf \red{h=25~m}$

Letra D

8)

$\sf x^2=3^2+4^2$

$\sf x^2=9+16$

$\sf x^2=25$

$\sf x=\sqrt{25}$

$\sf \red{x=5~m}$

9)

$\sf d^2+7^2=13^2$

$\sf d^2+49=169$

$\sf d^2=169-49$

$\sf d^2=120$

$\sf d=\sqrt{120}$

$\sf \red{d=2\sqrt{30}~milhas}$
