We will have the following:
First, we have that the problem can be seeing as follows:
Now, knowing this and the the properties of the diagonals we will have that [We use the law of cosines}:
First diagonal [AC} is given by:

So, one of the diagonals has an approximate length of 10.7 ft.
Second diagonal [BD] is given by:

So, the second diagonal has a length of approximately 28.1 ft.
<em>**Diagonals**</em>
Answer:
The answer is : b) a confound
Step-by-step explanation:
While manipulating, is possible that some factors like noise in the hall, can affect learning in one of the groups but not in the other.
This possibility reflects the presence of a confound.
We can define a confounding variable as an external influencing factor which results in bringing changes in the effects of a dependent and independent variable.
This variable changes the outcome of an experiment and produces useless results.
