Question 14915
suplementery angles are angles whos total add to 180 degrees
the problem would be
{{{n=4m-5}}}
and {{{n+m=180}}}
so for 4m-5 plug in n
{{{4m-5+m=180}}}
then combine like terms
{{{5m-5=180}}}
add 5 to moth sides
{{{5m=185}}}
divide both sides by 5
{{{m=37}}}
then plug 37 in for m
{{{n+37=180}}}
subtract from both sides
{{{n=143}}}
i hope that helps
