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? 40 50 100 160

Answer

Explanation:

Step1: Recall parallelogram angle - property

Adjacent angles in a parallelogram are supplementary (sum to 180°).

Step2: Set up the equation

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

Step3: Solve for (x)

(x=180^{\circ}- 80^{\circ}=100^{\circ})

Answer:

100
