1.	29. In fig. ABCD is a parallelogram. FindDx and y263x18AB3Y-1
Answer» In parallelogram , OPPOSITE sides are congruentThen AB=CD...2x+5=y+1.....2x-y=-4 .............(1)And AD+BC.....y+5=3x-4........-3x+y=-4-5=-9...........(2)Substructure (1) in to (2)-x=-13 Or x=13And y=-4-26=30Then AB=CD =2×13+5=31And AD+BC=3×13−4=35AB:AD=31:35
