Explanation:

Step1: Sum of interior angles of a quadrilateral

The sum of the interior angles of a quadrilateral is \(360^{\circ}\). So, \(5x + 5x+1x + 2x=360\).

Step2: Combine like - terms

Combine the \(x\) terms: \((5 + 5+1 + 2)x=360\), which simplifies to \(13x = 360\).

Step3: Solve for \(x\)

Divide both sides by 13: \(x=\frac{360}{13}\approx27.69\).

Answer:

\(x\approx27.69\)
