Given data:
The given figure is shown.
The expression for the angle 5 is,
[tex]\begin{gathered} \angle15+\angle16=180^{\circ} \\ \angle15+139^{\circ}=180^{\circ} \\ \angle15=41^{\circ} \\ \angle5=\angle15 \\ \angle5=41^{\circ} \end{gathered}[/tex]
The measurement of the angle 3 is,
[tex]\begin{gathered} \angle3=\angle5 \\ \angle3=41^{\circ} \end{gathered}[/tex]
Thus, the value of the angle 3 is 41 degrees.
