Question 1196524


if line {{{RQ }}}bisects line {{{DE}}} at {{{S}}}, than {{{ DS = ES }}}


if  {{{DS = 10 + 3x}}} and {{{ES = -2 + 6x}}}, than


{{{10 + 3x =-2 + 6x}}}.........solve for {{{x}}}

{{{10 + 2= 6x-3x}}}

{{{12= 3x}}}

{{{x=4}}}


now find {{{DS = 10 + 3x}}}

{{{DS = 10 + 3*4=22 }}}=>{{{ES =22}}}


then

 {{{DE= DS+ES }}}

 {{{DE=22+22}}}

 {{{DE= 44}}}
