Question

what is the value of q? 128.3°

Explanation:

Step1: Use the property of adjacent angles

Adjacent angles on a straight line sum to \(180^{\circ}\). So, \(q + 128.3^{\circ}=180^{\circ}\)

Step2: Solve for \(q\)

Subtract \(128.3^{\circ}\) from both sides of the equation: \(q = 180^{\circ}- 128.3^{\circ}\)
