Angle R and angle S are adjacent angles. In any parallelogram, this means they add to 180 degrees

R+S = 180
8n + 10n = 180
18n = 180
18n/18 = 180/18
n = 10

So n = 10. Let's use this to find the numeric value of S
S = 10n
S = 10*10
S = 100
Angle S is 100 degrees

And let's use n = 10 to find R
R = 8n
R = 8*10
R = 80
Angle R is 80 degrees
