The answer for the question is 60°

Destroyer48: so, x= 60°
Destroyer48: Sum of angles of traingle is 180°
AlkaKalra: Q 140 ku hai?
AlkaKalra: q*
Destroyer48: Mark it as brainliest plzz!!
Destroyer48: bola na sum of angles of triangle is 180°
Destroyer48: so, 20+20+angle Q= 180°
AlkaKalra: hmm but why is q 140 degree
Destroyer48: angle Q= 140°
Destroyer48: i said na

O is the center.
QR=OP
<ORP=20 degree
To find x.
OP=OQ       →1         [radii of the circle with center O]
But QR=OP   →2
From →1 and →2.
QR=OQ           
So <PRT=<ROQ=20 degree
<OQP=<PRT+<ROQ                  {exterior angle property}
          =20+20
<OQP=40 degrees
OP=OQ
So <OQP=<OPQ=40 degrees
<POQ=180 - <OQP - <OPQ                      {angle sum property}
          =180-40-40
<POQ=100 degrees
POR is a line.
So <POR=180 degrees
<ROQ+<POQ+<x=180
20+100+x=180
x=180-20-100
x=60 degrees
