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:
C =85
Step-by-step explanation:
n=180-133+180-142=47+38=85
48 i believe thats the best i can find
The coordinates of C are (a+c, b)
Coordinates of midpoint of AC are (a+c/2, b/2)
Coordinates of BD are (a+c/2, b/2)
