Question

Please try to solve these questions given below

Answer 1

Answer:

1) 35°

2) Figure is wrong either question is wrong it is not possible

3) Angle TQR = 20°

angle QTR = 130°

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.
