Hello!
The mean is 12
The data has a standard deviation of 4
Look and see how far away 18 is from 12 using 4
12 + 4 = 16
16 is one deviation
16 + 4 = 20
20 is two deviation
18 is right in the middle
The answer is C. 1.5 deviations
Hope this helps!

By means of that you can tell or figure out that the two triangle is congruent. So the answer is letter B. SAS
