Step-by-step explanation:
R' = (-2,0)
E' = (-2,2)
F' = (4,4)
Step 1
<u>Find the value of s</u>
we know that
In a Rhombus all sides are congruent
so


equate AB and CD

Combine like term


<u>The answer Part a) is</u>
the value of s is 
Step 2
<u>Find the value of side AB</u>

substitute the value of s

Remember that the sides are congruent

therefore
<u>the answer Part b) is</u>
The length of the side BC is 
Answer is 91.56 You add all the numbers up and divide by 9(There are 9 numbers in the sequence).
