Answer:

Step-by-step explanation:

Angle POT +Angle TOQ=180

Angle TOQ=40

OT=OQ (radii)

Angle OTQ=Angle OQT

Consider triangle TOQ

By angle sum property, Angle TOQ+AngleOTQ+Angle OQT=180.

2Angle OTQ=140

OTQ=OQT=70

Angle OQT+Angle RQT=180

Therefore,Angle RQT=110

Consider cyclic quadrilateral PQTS

Angle P+Angle T=180

Angle T=135

Angle STQ+Angle RTQ=180

Therefore,Angle RTQ=45
