If PQRS is a parallelogram, the value of 'x' is

70 35 55 25

25

PQRS is a parallelogram, thus opposite side are always parallel. Therefore, line SP is parallel to RQ. "According to parallel line concept : angles made on a straight line by two parallel lines are always equal, like shown in the below figure":- Thus, \(\angle\)SPQ = Exterior angle at Q x° + 45° = 70° x° = 70° - 45° = 25°
