Answer:
1) 35°
2) Figure is wrong either question is wrong it is not possible
3) Angle TQR = 20°

PLZ MARK ME AS THE BRAINLIAST.......
3rd method summary
angle PRQ = 60°
Angle PQR = 40° Sum of all angles in triangle
Angle TQR = 20° bisect of 40°
Angle QTR = 130° Using angle sum property of a triangle
1st is already solved
2nd is wrong because
Angle BCA = 60° Angle sum property of triangle
Angle ECD = 120° Linear pair
As EDC &ECD = 180° it is wrong.
