Question

question find the measure of the missing angle. answer attempt 3 out of 99 y= °

Explanation:

Step1: Recall angle - sum property

The sum of angles on a straight - line is 180°.

Step2: Set up the equation

Let the missing angle be \(y\). We have \(y + 77^{\circ}=180^{\circ}\).

Step3: Solve for \(y\)

\(y=180^{\circ}-77^{\circ}\).
\(y = 103^{\circ}\)

Answer:

103
