To determine the value of n in the angle pair above, we can use the fact that angles on a straight line add up to 180 degrees.
Let's denote the unknown angle as x. The given angle is 12 degrees. Since these two angles form a straight line, they add up to 180 degrees.
So, the equation becomes:
x + 12 = 180
Solving for x, we get:
x = 180 - 12
x = 168
Therefore, n = 168.
