Question

in parallelogram ABCD,AB=9x-2,CD=7x+8,BC=2y-3 find the values of x and y pls step by step
​

Answer 1

Step-by-step explanation:

In parallelogram , opposite sides are congruent

Then AB=CD...2x+5=y+1.

2x-y=-4 (1)

And AD+BCy+5=3x-4

-3x+y=-4-5=-9..(2)

Substructure (1) in to (2)

-x=-13 Or x=13

And y=-4-26=30

Then AB=CD =2×13+5=31

And AD+BC=3×13−4=35

AB:AD=31:35
