Answer:
110 degrees
Step-by-step explanation:
<PQR=<PRQ(isocles triangle)
<QPR=180-(40+40)
=100
<QTR=180-<QPR (sum of the opposite angles of a cyclic quadrilateral is 180)
=180-100
=80
<QOR=2 x <QTR (angle substended in the circumference is half of the angle at center)
=2 x 80
= 160
<QSR=<QPR (corresponding angles are equal)
= 100
