Answer:

#/_QSR=78^@#

Explanation:

As #QR# subtends the angles #/_QPR# and #/_QSR# on thesame side of chord #QR#, thetwo are equal i.e.

#/_QSR=/_QPR#

As #QS# is bisector of #/_PQR# and #/_SQR=35^@#

#/_PQR=2xx35^@=70^@#

Now in #DeltaPQR#, we have #/_PQR=70^@# and #/_PRQ=32^@#

Hence #/_QPR=180^@-70^@-32^@=78^@#

and #/_QSR# too is #78^@#.
