properties of parallelograms
example: consecutive angles supplementary.
answer: round to whatever you see in the problem.
ok

Explanation:

Step1: Set up the equation

Consecutive angles in a parallelogram are supplementary. So \((11x - 10)+8x=180\).

Step2: Combine like - terms

Combine \(11x\) and \(8x\): \(19x-10 = 180\).

Step3: Isolate the variable term

Add \(10\) to both sides: \(19x-10 + 10=180 + 10\), which gives \(19x=190\).

Step4: Solve for \(x\)

Divide both sides by \(19\): \(\frac{19x}{19}=\frac{190}{19}\), so \(x = 10\).

Answer:

\(x = 10\)
