Answer:
The measure of angle N is 141°.
Step-by-step explanation:
From the given figure it is noticed that the angle 39° and angle N lies on a straight line. It means both angles are supplementary angles.
If two angles are known as supplementary angles, then their sum is 180°.
Since angle 39° and angle N are supplementary angle, therefore their sum is 180°.
\(\angle N+39^{\circ}=180^{\circ}\)
Subtract 39 from both sides.
\(\angle N=180^{\circ}-39^{\circ}\)
\(\angle N=141^{\circ}\)
Therefore the measure of angle N is 141°.
