Question

in the isosceles triangle PQR the vertice angle P=50° the circle passing through Q and R cuts PQ in S and PR in S and T is joined Find angle PST​

Answer 1

Answer:

The value of the angle PST is 65°

Answer 2

Answer:

rqst will form cyclic quadrilateral

then angle pst =angle prq ext property of cyclic quadrilateral

angle prq =(180-50) /2=65°

since pq =pr
