Question

plzz plzz solve ihave board exam

Answer 1

hello friend!!

join RQ

angle RQS=1/2 Ang ROS=21degree
angle PRQ=90 degree .......................angle in same circle

angle PRQ+TRQ=90 degree........................linear pair..

therefore. TRQ=90(can be seen) by above.

now..use angle sum property in angle( T+r+Q)= 180.

hence,angle RTS= 69 degree.
answer :))
thanks!
