Question

7. Determine as medidas de b, c, h e m​

Answer 1

Resposta:

 m= 9

 c =20

b = 15

h = 12

Explicação passo a passo:

a=m+n

25=m+16

-m=16-25 (-1)

m=9

$h^{2} = m.n$

$h^{2} =16.9\\h^{2} =144\\h=\sqrt{144} \\h=12$

$b^{2} =m^{2} +h^{2} \\b^{2} =9^{2} +12^{2} \\b^{2} = 81+144\\b^{2} = 225\\b=\sqrt{225} \\b=15$

$a^{2} =b^{2} +c^{2}\\25^{2} =15^{2} +c^{2}\\-c^{2} = 225-625 (-1)\\c^{2} = 400\\c=\sqrt{400} \\c=20$
