The circle graph shows the distribution of age groups of people living in a city. Identify the measure of arc PR. HELP ASAP!!

Answer:
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°
