suplementery angles are angles whos total add to 180 degrees
the problem would be
n=4m-5
and n%2Bm=180
so for 4m-5 plug in n
4m-5%2Bm=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%2B37=180
subtract from both sides
n=143
i hope that helps
