Question

Find the value of x in the

following parallelogram:
2x - 1
11
7
x = [?]

Answer 1

`x = 4`

Explanation:

See attachment for complete question

From the attachment, the parallelogram has two diagonals. And the diagonals of a parallelogram bisect one another.

Because 2x - 1 and 7 are opposite sides of a diagonal; We can say that:

`2x - 1= 7`

Add 1 to both sides

`2x - 1 + 1 = 7 + 1`

`2x = 8`

Divide through by 2

`x = 4`
