Question

Encontrar los lados faltantes

Answer 1

Respuesta:

a) a= 2 \sqrt{19}

b) c= sqrt{89}

c) b= 5 \sqrt{5}

d) c= sqrt{202}

Explicación paso a paso:

$20^{2} = 18^{2} +x^{2}$

400 - 324 = $x^{2}$

76= x^{2}

$2 \sqrt{19}$=x

-----------

$8^{2} + 5 ^{2} = x^{2}\\64 + 25 = x^{2}\\89 = x^{2}\\\sqrt{89} =x$

---------------

$10^{2} + x^{2} = 15^{2} \\100 + x ^{2} =225\\x^{2} =225 - 100\\x^{2} =125\\x = 5\sqrt{5}$

------------------

$9^{2} +11^{2} =x^{2} \\81 + 121 =x^{2} \\\sqrt{202} = x$
