Answer:</h2>
An angle measures how how much you have to rotate one line called <em>initial side</em> so it lies on the top of other line called the <em>terminal side. </em>Angles whose vertex is located at the origin having the initial side on the positive x-axis is said to be in standard position. On the other hand, coterminal angles are angles in standard position having the same terminal side. In this way, for the angle:

Okay so you're correct answer in this situation would be A but it could alsobe C
We know that the sum of the internal angles in each triangle is 180°.
Therefore we have the equation:

substitute and solve:

We have

substitute the value of x to the expression:

Answer: m∠N = 42 degrees
C would be the correct answer
A would mean that 6=3*18, which is incorrect
B would mean that 3=6*18 which is also incorrect
C would mean that 18=6*3 which is CORRECT
D would mean that 18=6*2 which is also incorrect
Therefore, C would be the correct answer
