In the adjoining figure, ABCD is a trapezium in which `CD||AB` and its diagonals intersect at O. If `AO=(5x-7) cm, OC=(2x+1) cm, DO=(7x-5) cm` and `OB=(7x+1) cm`, find the value of x.

In the adjoining figure, ABCD is a trapezium in which CD||AB and its diagonals intersect at O. if AO= (5x-7) cm, OC =(2x+1)cm, BO=(7x-5) cm and OD =(7x+1)cm , find the value of x.

In the given figure, ABCD is trapezium whow diagonals AC and BD intersect at O such that OA=(3x-1) cm, (OB=(2x+1) cm, OC=(5x-3) cm and OD =(6x-5)cm . Then, x=?

ABCD is a trapezium in which AB parallel to DC and its diagonals intersect at P. If AP = (3x - 1) cm, PC = (5x - 3) cm, BP = (2x + 1) cm and PD = (6x - 5) cm, then the length of DB is: ABCD एक समलम्ब है जिसमें AB, DC के समानांतर है तथा इसके विकर्ण P पर एक दूसरे को काठते हैं | यदि AP = (3x - 1) सेमी, PC = (5x - 3) सेमी, BP = (2x + 1) सेमी तथा PD = (6x - 5) सेमी है, तो DB की लंबाई क्या होगी ?
