Diagonals of a quadrilateral PQRS bisect each other. If angle P=145`, determine the angle Q

if the diagonals of any quadrilateral bisect each other then it can be said that it is a parrlellogram. by its property PS will be parrellel to QR andpq will act as transversal so the sum of cointerior angles will be 180 thus
anglep+angleq=180
145+x =180
x=35 that is angle p is 35
