Question

what is the value of k?

Explanation:

Step1: Use the linear - pair property

The sum of angles in a linear pair is \(180^{\circ}\). Let the two angles be \(110^{\circ}\) and \(k\). So, \(110 + k=180\).

Step2: Solve for \(k\)

Subtract \(110\) from both sides of the equation \(k = 180-110\).

Answer:

\(70\)
