Answer:
the stated ratio means that of the 180 degrees involving two supplementary angles, the smaller angle is one sixth of that whole. Thus the smaller angle measures 30 degrees & the larger measures 150 degrees.
Step-by-step explanation:
It's 4800, just multiply 60x80 bc the population is 80x larger than the sample of 100
80cm^2
20*5=100
10*2=20
100-20=80
(8,1)
I think its C. I'm not sure I havent been thought this lesson.
