Question

In given figure, AB || DC, find the value of x.
​

Answer 1

if a b parallel to dc so it would be a trapezium because the size of the two other side is not given now we know that a b is equals to DC

so the diagonal DB and ac is equals to X - 2 and X - 1

Db = x-2+ x-1= 2x-3 = x= -3/2. or -1×1/2

in,

AC = x-3 + X+5 = 2X + 2 = X= 2/2 or 1
