Question

alguém me ajuda a responder pfv

Answer 1

Resposta:

$a)4\sqrt{6}\\b)6\sqrt{3}$

Explicação passo-a-passo:

$A)\\\\l = 8\sqrt{2} \\\\h = \frac{8\sqrt{2} \sqrt{3}}{2} = 8 : 2 * \sqrt{2*3} = 4\sqrt{6} \\\\B)\\\\h = \frac{l\sqrt{3} }{2} \\\\\sqrt{27} = \frac{l\sqrt{3} }{2}\\\\\sqrt{27} = \sqrt{3*3*3} = 3\sqrt{3} \\\\\frac{l\sqrt{3} }{2} = 3\sqrt{3}\\\\l\sqrt{3} = 2*3\sqrt{3} = 6\sqrt{3}$

Espero ter ajudado!
