Answer 1

PQ=PR
SO,<pqr=<prq


Sum of all angles of triangle is 180°
so,
<pqr+<prq+<qpr=180°
<pqr+<prq+30=180

2<pqr=150
<pqr=75
<pqr=<prq=75
As,
<rqp=<rsq (because there is rule that angle between tangent and chord is equal to the
angle opposite to the chord to which end points of chord joined together to form in circumference of circle)
So,
<rsq=75
It is given that
SR||QP
SO,
<rsq+<pqs=180 (sum of angle to same side of transversal)
75+<pqs=180 (as<rsq=75)
<pqs=105
(<pqs=<pqr+<qrs)
105=75+<qrs
<qrs=30°
