Question

plz and this question

Answer 1

Triangle PST congruent Triangle QRT
PS=QR
ST=TR
AnglePST = angle QRT (90+60 both)
So
PT=QT CPCT
TR=SR=RQ
Angle RTQ=AngleRQT
2angle TQR=180-150 angle sum property
Angle TQR=30/2=15

Answer 2

 I)  PT=QT     (beacause PS=RQ   & ST=TR)

 II) ANGLE  TQR =15  

                     Triangle STR is equilateral 
                     so, all angle is 60
                     


                  then angle TQR is 15
