Question 1128180


Determine {{{m}}} < {{{a}}},  {{{m}}} < {{{b}}},  {{{m}}} < {{{c}}}

angle in triangle, and their sum is {{{180}}}

so, if


 {{{m}}} < {{{a= 3x + 5}}}
 {{{m}}} < {{{b= 5x - 18}}}
{{{m}}} < {{{c=7x - 2}}}

we have

{{{ 3x + 5+5x - 18+ 7x - 2=180}}}

{{{ 15x- 15=180}}}

{{{ 15x=180+15}}}

{{{ 15x=195}}}

{{{ x=195/15}}}

{{{ x=13}}}


{{{m}}} < {{{a= 3x + 5=3*13+5=44}}}
 {{{m}}} < {{{b= 5x - 18=5*13-18=47}}}
{{{m}}} < {{{c=7x - 2=7*13-2=89}}}
