Three important properties of the diagonals of a rhombus that we need for this problem are: 
1. the diagonals of a rhombus bisect each other 
2. the diagonals form two perpendicular lines 
3. the diagonals bisect the angles of the rhombus
First, we can let O be the point where the two diagonals intersect (as shown in the attached image). Using the properties listed above, we can conclude that ∠AOB is equal to 90° and ∠BAO = 60/2 = 30°. 
Since a triangle's interior angles have a sum of 180°, then we have ∠ABO = 180 - 90 - 30 = 60°. This shows that the ΔAOB is a 30-60-90 triangle.
For a 30-60-90 triangle, the ratio of the sides facing the corresponding anges is 1:√3:2. So, since we know that AB = 10, we can compute for the rest of the sides.



Similarly, we have



Now, to find the lengths of the diagonals, 


So, the lengths of the diagonals are 10 and 10√3.
Answer: 10 and 10√3 units
 
        
        
        
Answer:
3²
Step-by-step explanation:
We have to use BPEMDAS Order of Operations:
B - Brackets
P - Parenthesis
E - Exponents
M - Multiply
D - Divide
A - Addition
S - Subtraction
We use this order left to right. Since we have parenthesis, we look at that first. Inside, we have division and exponents. Since exponents come first, we have to evaluate 3² first.
 
        
                    
             
        
        
        
Answer:
y=2
Step-by-step explanation:
Multiply -3(2) which gives -6, -6+8=2
Thus, y=2
 
        
             
        
        
        
Total area = 104+24 = 128 sq.in ,  Option C is the right answer.
The missing figure is attached with the answer.
<h3>What is Area ?</h3>
The space occupied by a two dimensional figure is called Area.
The figure given in the question can be divided into two figure 
A rectangle of 8 * 13 inch
and a triangle of 8 * 6 inch
The area of a rectangle is given by 
Length * Breadth
8 * 13
= 104 sq.inch
The area of the triangle is given by
(1/2) * base * height
= (1/2) * 8 * 6
= 24 sq.inch
Total area = 104+24 = 128 sq.in
Therefore Option C is the right answer.
