Question

student belcher, cash
properties of parallelograms
solve for the unknown
variable (x).
answer: round to whatever you
see in the problem.
ok

Explanation:

Step1: Use property of parallelogram

In a parallelogram, opposite angles are equal. So, \(\angle GFE=\angle GDE\).

Step2: Set up equation

We have \(2x + 18=40\).

Step3: Solve for \(x\)

Subtract \(18\) from both sides: \(2x=40 - 18\), so \(2x = 22\).
Divide both sides by \(2\): \(x=\frac{22}{2}=11\).

Answer:

\(11\)
