The measure of VW is 6. It's because since the figures are congruent their names are written in correspondence ....so since VW corresponds to CD , the answer must be 6.
Answer:
B. 21.64
Step-by-step explanation:
We have been given a triangle and we are asked to find the length of AC (b).
We will use law of cosines to find the length of side AC.

Upon substituting our given values in the formula we will get,
Upon taking square root of both sides of our equation we will be get,
Therefore, the length of b is 21.64 and option B is the correct choice.
Answer:
you given me only 25 point
4cm, as if two of the sides add up to be the same length as the first side then the triangle would be a straight line.

Answer:

Step-by-step explanation:
- <em>Take into account that a population data set contains all members of the group and a sample data set contains only a subpart of the group.</em>
<em />
- <em>In this case, Ms. Smith can take the scores of all students of the math class, due to this group is not enough big to consider to take a subpart.</em>
<em />
<u><em>Hence, Ms. Smith should consider her data as a population data set.</em></u>
