angle cbp will be 180-120 degree.
reason- co interior angles
angle spq will be 50 degree
reason- opp. sides of parrelelogram are equal
therefore angle x will be 180-(60+50)
reason-aspt
so angle x = 70 degree

because in ABCD, ABllDC
DAB= BCD =120 (oppos. angle of parallelogram are equal)
SRQ = QPS =50 ( " )
OPS =PSD =50 =OSC .......( i )
OCS =180-BCD =180-120 =60
In triangle CSO :
OCS +OSC +COS =180 (Angle sum property of triangle)
50 +60 +COS =180 ; 110 +COS =180 ; COS =180 -110= 70
COS = x = 70 _vertically opposite angle)
Ans : x=70
