Question

what is the value of w? 102° submit

Explanation:

Step1: Use the concept of a straight - line angle

The sum of angles on a straight line is \(180^{\circ}\). So, \(102^{\circ}+w = 180^{\circ}\).

Step2: Solve for \(w\)

Subtract \(102^{\circ}\) from both sides of the equation: \(w=180^{\circ}- 102^{\circ}\).

Answer:

\(78\)
