Since k and j are parallel, angle 4 is equal to the angle to the left of 60 degrees. Since j is a line, the angle to the left of 60 added on to 60 is 180.
180 -60 = 120. The angle is 120 degrees.
Since angle 4 is equal to that angle, angle 4 is also 120 degrees.
An exterior angle is found outside the parallel line. When you have two exterior angles that are opposite each other along the transversal, they are referred to as alternate exterior angles.
Therefore, the only pair of angles from the given options that flare alternate exterior angles are:
1.The heights of students in a class, for example, would have a normal distribution. We expect a few students to be extremely tall and a few to be extremely short, but the majority will be in the middle. On the x-axis, we'll have heights, and on the y-axis, we'll have the frequency of the number of students with heights. According to the empirical rule, 68 percent of the data could fall within one standard deviation of the mean.
