The measure of an angle is eight times the measure of a supplementary angle. what is the measure of each angle? on ixl

Let one angle be x
Let second angle be 8x
Sum of supplementary angles = 180°
x+ 8x = 180°
9x = 180
x = 180/9 = 20

First angle= x= 20°
Second angle = 8x = 8*20 = 160°
I hope it is helpful:D
