Please help me i only know what w is

w=23,x=126,y=119

Step-by-step explanation:

w=23

3(23)-15=54

opposite angle = 54

360-(54+54)=252

252÷2=126

x=126

180-61=119

y=119

B is correct not C

Step-by-step explanation:

In a parallelogram opposite angles are equal means Angle QST = Angle QRT.

Also in parallelogram diagonals bisect each other means Angle QSR= Angle TRS but not Angle QSR = Angle TSR
