Pq nd PR are tangents
PQ=PR
Angle PQr=PRQ
In triangle pqr
60+2anglepqr=180 (asp)
Angle pqr =60
Take any pt. A on the corr. Alt. Segment
Join QA nd RA
Angle QAR=angle PQR (angles in alt. Segment are equal)
Angle QAR=60
Angle qsr +qar=180 (aqsr is cyclic quadrilateral)
Angle qsr =180-60
Angle qsr=120
