Answer:
angle PQR = 125° if angle POR = 110°
Step-by-step explanation:
angle POR = 110°
360°- 110° = 2* angle PQR
=> 250° = 2* angle PQR
=> angle PQR = 250/2 = 125°
=> angle PQR = 125°
Another method:-
Take a point M on arc PR ( arc other than arc angle PQR)
then PMQR will be cyclic quadrilateral
angle PMR + angle PQR = 180°
angle POR = 2* angle PMR
=> 2* angle PMR = 110°
=> angle PMR = 110/2 =55°
=> angle PMR = 55°
=> 55 °+ angle PQR = 180°
=> angle PQR = 55 - 180 =125°
=> angle PQR = 125°
