Since angle 16 measures 139 degrees and is a supplementary angle with angle 17, we have the following equation:


139+\measuredangle17=180

solving for angle 17, we get:


\begin{gathered} 139+\measuredangle17=180 \\ \Rightarrow\measuredangle17=180-139=41 \\ \measuredangle17=41\degree \end{gathered}

therefore, the measure of angle 17 is 41 degrees
