Question

Find the value of x in the
following parallelogram:
2x - 1
11
7
x = [?]

Answer 1

Answer:

$x = 4$

Step-by-step 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

$x = 4$
