Question

find the measure of the missing angle. 65° a

Explanation:

Step1: Use the property of adjacent angles on a straight line

Adjacent angles on a straight line sum to \(180^{\circ}\).
So, \(65^{\circ}+a = 180^{\circ}\)

Step2: Solve for \(a\)

Subtract \(65^{\circ}\) from both sides of the equation.
\(a=180^{\circ}- 65^{\circ}\)
\(a = 115^{\circ}\)

Answer:

\(115^{\circ}\)
