Question

yolanda is making a banner for a school pep rally she cuts fabric in the shape of a parallelogram the angle at the bottom - left corner measures 80° what is the value of x?

Explanation:

Step1: Recall the property of adjacent angles in a parallelogram

In a parallelogram, adjacent angles are supplementary. That is, the sum of adjacent angles is \(180^{\circ}\).

Step2: Set up the equation

Let the given angle \(80^{\circ}\) and \(x^{\circ}\) be adjacent angles. Then the equation is \(x + 80=180\).

Step3: Solve for \(x\)

Subtract \(80\) from both sides of the equation: \(x=180 - 80\).

Answer:

\(100\)
