=90°+60°+2x°+x°=360°
=150°+3x°=360°
=3x=360°-150°
=3x=210°
=x=70°
R= 2x........(given)
R=2*70
R=140°
No. of participants from school S=60°
therefore, 140°=28
So, no.of participants in school R is 28..
Hope it helps ✌✌ PLEASE IT AS BRAINLIEST........

it is very easy.....
ATQ
90 + 2x + 60 + x = 360°
3x + 150 = 360°
3x = 210°
x = 70°
SO...
2x = 2 × 70 = 140°
NOW,,,
ANGLE FOR 1 STUDENT=
60°/12 = 5°
no. of participants from school R is
140°/5° = 28
hope this helps you
