reflex angle por =200
in triangle opr .. angle Opr = 360-200
160 .
in triangle Por..
op = or ( radius )
x + x + 160 = 180
2x = 20
x = 10..
angle Opr =20
hope this helps u simply if you like plz mark it as brainliest

angle POR=160 degree
construct two linees from P And R on the below side meeting at one point
a cyclic quadrilateral will be formed
using property that sum of opposite angles is 180
therefore constructed 2 lines will subtend 80 degree angle on the circumfrence
now use property that angle subtended by a chord at circumfrence is half the angle subtended at center
we wil get por=160
now por is isosceles triangle
let opr be x
2x+160=180
x=10°
plz tell if right or wrong
