Question

AD||CB
AB||CD
m2A = 90
AC = 8
find DE​

Answer 1

Answer: DE is 4

Explanation:

Alright, lets get started.

Since given that AD is parallel to CB.

And AB is parallel to CD.

And the angle A is given as 90°

It means the given figure is a rectangle.

And the diagonals of the rectangle are equal to each other.

So,
`DB=AC`

So,
`DB=8`

Now the diagonals bisects each other. So

`DE=(DB)/(2)`

`DE=(8)/(2)`

`DE=4`

Hence the answer is 4 ... Answer
