Well.....that's quite a bit !! LOL!!!
But if POV and SOR are supplementary.....then we have
2x + 80 + 3x = 180
5x + 80 = 180 subtract 80 from both sides
5x = 100 divide by 5
x = 20
SOR = 3(20) = 60
POV = 2(20) + 80 = 120
POS = 5(20) + 10 = 110
VOR = 360 - 60 - 120 - 110 = 70
arc SR = 60
arc RV = arc VR = 70
arc PV = 120
arc PS = 110
arc SPV = 110 + 120 = 230
arc VSP = 360 - 120 = 240
arc RPV = 360 - 70 = 290
