Question 802412
-------------------------------------------------
measure of one of two supplementary angles is 20 degrees more than 7 times the measure of the other, 
---------------------------------------------------


x, the other angle measure
7x+20, the one of two angle measures



{{{x+(7x+20)=180}}}

-

{{{8x+20=180}}}

{{{8x=160}}}

{{{x=20}}}


Does this work?
{{{20+(7*20+20)}}}
{{{20+140+20}}}
{{{140+20+20}}}
{{{180}}}{{{okay}}}


20 degrees and 160 degrees
