## anonymous one year ago The ratio of the measures of two supplementary angles is 7:8. Which proportion(s) could you use to find the measures of the angles?

This is multiple choice, some of the answers are: x/y= 7/8 x/y=8/7 x/180-x=7/8 x/180-x=8/7

Thanks for replying, how did you come to this conclusion?

$x+y=180,y=180-x$ $\frac{ x }{ y }=\frac{ x }{ 180-x }=\frac{ 7 }{ 8 }$
