Similar triangles may or may not be congruent.
The congruent criterion to use in her proof is (b) SAS theorem
From the question, we understand that she draws an angle bisector from to side PR
This means that, either sides of angle Q are congruent. (this is represented by A i.e. angle)
When is bisected, sides PB and RB become congruent
i.e. ... (this is represented by S i.e. side)
Lastly, both triangles share a common side at QB .. (this is also represented by S i.e. side)
So, we have: SAS
Hence, the congruent criterion to use in her proof is (b) SAS theorem

Answer:
Her height, in inches, is closest to 70.
Step-by-step explanation:
This can be solved by the the z-score formula:
On a normaly distributed set with mean and standard deviation
, the z-score of a value X is given by:
Each z-score value has an equivalent p-value, that represents the percentile that the value X is:
In this problem, we have that:
A z-score of 2.33 has a p-value of 0.9901. This means that a height with a z-score of 2.33 is in the 99th percentile.
So, what is the value of X when
Her height, in inches, is closest to 70.
