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>
Given:
To find:
The missing value.
Solution:
Let x be the missing value.
We have,
Subtract from both sides.
Multiplying both sides by 5, we get
So, the missing value is 3.
Therefore, the correct option is C.
