Question

What is the measurement of ∠N?

Answer 1

The measure of N is 141. The straight line is 180 so is you subtract 39 from 180 you get 141.

Answer 2

The measure of angle N is 141°.

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°.
