the diagnol of a rectangle PQRS meet at point O.if anglePOQ=124.find angleOSR

As angle POQ is 124 degree

Hence SOR is vertically opposite angle so it is 124

In triangle SOR , side SO = OR (diagonals of a rectangle are equal and bisect each other)

So the angle OSR = angle ORS

And sum of angle of triangle = 180

Hence 124 + OSR + ORS = 180

So 2OSR = 180- 124

OSR = 56/2 = 28
