Question

what is the value of v?

Explanation:

Step1: Use the linear - pair property

The sum of angles in a linear pair is \(180^{\circ}\). If one angle is \(80^{\circ}\) and the other is \(v\), then \(80 + v=180\).

Step2: Solve for \(v\)

Subtract \(80\) from both sides of the equation \(80 + v=180\).
\(v = 180-80\).

Answer:

\(100\)
