Question

the quadrilateral is a parallelogram. find the measure of angles 1, 2, and 3. 5. measure of angle 1? type a response show your work

Explanation:

Step1: Use the property of parallelogram (adjacent angles are supplementary)

In a parallelogram, adjacent angles are supplementary. So, \(\angle1 + 80^{\circ}=180^{\circ}\)

Step2: Solve for \(\angle1\)

\(\angle1=180^{\circ}- 80^{\circ}\)

Answer:

\(100^{\circ}\)
