Question

find the value of x in parallelogram rstu.

Explanation:

Step1: Recall parallelogram property

In a parallelogram, opposite - sides are equal. So, $8x=x + 28$.

Step2: Solve the equation for x

Subtract $x$ from both sides: $8x−x=x + 28−x$. This simplifies to $7x=28$.

Step3: Isolate x

Divide both sides of the equation $7x = 28$ by 7: $x=\frac{28}{7}$.

Answer:

$4$
