Question

Help me please i cant seem to get it

Answer 1

The diagnonals of a parallelogram bisect each other ,

so

=》 BD = 3x × 2

=》BD = 6x

and there's given that

=》

`BD = (3)/(5) AC`

=》

`6x = (3)/(5) * 40`

=》

`x = (24)/(6)`

=》

`x = 4`

so, if x = 4 , then the given quadrilateral is a parallelogram.
