Given: Three intersecting lines

To Determine: how w would be found

Solution

Label the diagram

From the above, angles 1, w, and w lies on the same straight line

Also 76⁰ and angle 1 are vertically opposite angles. the sum of angles on a straight line is 180⁰

Therefore


\begin{gathered} w+w+76^0=180^0 \\ 2w+76^0=180^0 \end{gathered}

In summary, to find w, we would find the angle that is vertically opposite to 76⁰. Then use sum angles on a straight line to get the value of w since 2w and 76⁰ lies on the same straight line
