Answer and Step-by-step explanation:

$Greetings!$

$Let's~answer~your~question!$

$Since~ we~ know~ that ~these ~two~ are~ similar, ~it ~is ~also~ given ~that~ corresponding\\ parts ~of ~the~ triangle~ are ~proportional.~ In ~result,~ you~ can~ set~ the~ proportions~\\something~ like~ this:$

$\frac{16}{32}= \frac{12}{24}$

$Now,~from~ here, you~ can ~figure~ out~ that~ the~ ratio~ of ~the ~larger ~triangle~ to ~the \\~smaller~ triangle~ is ~.75:1$

$You~can~ then~ apply~ this~ to~ the~ side ~of ~x-1 ~and ~set~ up ~the~ equation.$

$.75(x-1)=6$

$Now,~solving~ the~ equation,~ you~ get~ x=9.~ Substitute~ that~ into~ x-1~ and~ you\\ get~ 8 ~as ~that~ side~ length.~ To~ check, compare:$

$\frac{8}{6}=\frac{32}{24}$

$Thus,~the~value~of~x~is=9.$

$Hope~my~answer~helps~you!~Have~a~blessed~day~ahead!$
