3. Make a conjecture: What happens to m ZAJK, M ZBKI, and m 2CLJ as
you change the line of reflection?
L. The angles change.
The angles do not change
The angles are always right
angles.

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

What term best describes a line ans a point that lie in the same plane

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.1. (round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51?
