Question

figure abcd is a parallelogram. what is the value of x? 6 7 8 9

Explanation:

Step1: Use property of parallelogram

In a parallelogram, opposite sides are equal. So, \(AD = BC\). Given \(AD=5x + 3\) and \(BC = 38\), we get the equation \(5x+3=38\).

Step2: Solve the equation for \(x\)

Subtract 3 from both sides: \(5x+3 - 3=38 - 3\), which simplifies to \(5x=35\).
Divide both sides by 5: \(x=\frac{35}{5}\).

Answer:

\(7\)
