Question

2 .. + 30 Given the parallelogram to the right, find x. * (1 Point) 130 50" 50" 130 2.x 40 70 100 20 O 45

Answer 1

In a parallelogram, the opposite sides are parallel and congruent (they have the same length).

So we can write the following equation comparing the sides x + 30 and 2x - 40:

$\begin{gathered} x+30=2x-40 \\ 2x-x=30+40 \\ x=70 \end{gathered}$

So the value of x is 100, therefore the correct option is the second one.
