Question 398122
use Pythagorean Theorem

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

if one leg of a right triangle is {{{a=6 m}}} and the hypotenuse is {{{c=12 m}}}, the approximate length of the second leg {{{b}}} is:

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

{{{(12 m)^2 = (6 m)^2 + b^2}}}

{{{b^2 = (12 m)^2 - (6 m)^2}}}

{{{b^2 = 144m^2 - 36m^2}}}

{{{b^2 = 180m^2 }}}


{{{b = sqrt(180m^2) }}}

{{{b = 13.416m }}}


the approximate length of the second leg is {{{b = 13m }}}
