Question

hola necesito la respuesta ><​

Answer 1

Respuesta:

A)

$a^{2} +b^{2} =c^{2}$

$55^{2}+12^{2}= x^{2}$

$435600= x^{2}\\\sqrt{435600}= \sqrt{ x^{2}\\} \\660= x$

B)

$x^{2}+9^{2}= 41^{2}\\x^{2}= 41^{2}- 9^{2}\\\sqrt{x^{2}}= \sqrt{ 1600\\} \\40= x$

C)

$x^{2}+21^{2}= 29^{2}\\x^{2}= 29^{2}- 21^{2}\\\sqrt{x^{2}}= \sqrt{ 400\\} \\20= x$

a)

$x^{2}+55^{2}= 305^{2}\\x^{2}= 305^{2}- 55^{2}\\\sqrt{x^{2}}= \sqrt{90000\\} \\300cm= x$

b)

$x^{2}+1.8^{2}= 8.2^{2}\\x^{2}= 8.2^{2}- 1.8^{2}\\\sqrt{x^{2}}= \sqrt{64\\} \\8= x$

c)

$36^{2}+15^{2}= x^{2}\\1521= x^{2}\\\sqrt{1521}= \sqrt{ x^{2}\\} \\39= x$
