hope it helps you mark as brainliest

Answer 2

total degre of a circle=360°
value of x
x+2x+150=360
3x=360-150
3x=150
×=150/3
x=50
then 2x= 50×2
2×=100
let the no. of participants in R be x
we can solve the question by cross multiplication
if 60°=18
then 100°=x
60/100=18/x
60*x=100*18
x=100*18/60
x=10*18/6
x=10*3
x=30
