Question

me resuelven el ejercicio con la operatoria.

Answer 1

Explicación paso a paso:

A)

${37}^{2} = {35}^{2} + {x}^{2} \\ 1369 = 1225 + {x}^{2} \\ 1369 - 1225 = {x}^{2} \\ 144 = {x}^{2} \\ \sqrt{144} = x \\ 12 = x$

$p = 2b + 2h \\ p = 2(35) + 2(12) \\ p = 70 + 24 \\ = 94 \: cm$

B)

${10}^{2} = {8}^{2} + {x}^{2} \\ 100 = 64 + {x}^{2} \\ 100 - 64 = {x}^{2} \\ 36 = {x}^{2} \\ \sqrt{36} = x \\ 6 = x$

$6 + 6 = x \\ 12 = x$

$p = 5l \\ p = 5(12) \\ p = 60 \: cm$
