Answer:


Step-by-step explanation:

Const.=Join QT

Angle QOT=180°-Angle POT

=180°-140°

=40°

IN triangle TOQ,

OT=OFQ

angle OTQ=angle OQT=X

angle (OTQ+OQT+QOT)=180°

40°+x+x=180°

40°+2x=180°

2x=140°

x=70°

Angle OTQ=Angle OQT=70°

angle RQT=180°-angle OQT

=180-70

=110

PQTS is a cyclic quadrilateral,

angle RTQ=angle SPQ=45°

Hence angle RTQ=45°
