Explicación paso a paso:

a)

[tex]d = \sqrt{ {(12)}^{2} + {(5)}^{2} } = \sqrt{144 + 25} [/tex]

[tex]d = \sqrt{169} = 13 \: cm[/tex]

b)

[tex]c = \sqrt{ {(30)}^{2} - {(18)}^{2} } = \sqrt{900 - 324} [/tex]

[tex]c = \sqrt{676} = 26 \: cm[/tex]

c)

[tex]c = \sqrt{ {(20)}^{2} - {(16)}^{2} } = \sqrt{400 - 256} [/tex]

[tex]c = \sqrt{144} = 12 \: cm[/tex]
