The circle graph shows the distribution of age groups of people living in a city. identify the measure of arc pr.

100.8°

Step-by-step explanation:

∠POR = ∠POQ + ∠QOR

∠POQ is 20% of 360° ( measure of the angles in a circle )

= 0.2 × 360° = 72°

∠QOR is 8% of 360° = 0.08 × 360° = 28.8°

Hence

arc PR = ∠POR = 72° + 28.8° = 100.8°

though don't really understand the question

Step-by-step explanation:

i would say

y= nx

y=180

so 180=n5

divide both sides by 5

180/5= 36

the answer is D= 36
