Respuesta:
[tex]a^{2}[/tex] = [tex]15^{2}[/tex] + [tex]20^{2}[/tex]
[tex]a^{2}[/tex] = 225 + 400
[tex]a^{2}[/tex] = 625
a = [tex]\sqrt{625}[/tex]
a = 25
Explicación paso a paso:
[tex]24^{2}[/tex] = [tex]12^{2}[/tex] + [tex]b^{2}[/tex]
576 - 144 = [tex]b^{2}[/tex]
432 = [tex]b^{2}[/tex]
[tex]\sqrt{432}[/tex] = b
20.784609690827 = b
espero te sirva
