In a rhombus, the diagonals meet at right-angles, and they bisect each other, namely they cut each other in half, check the picture below.
thus we can use the pythagorean theorem to get one side, keeping in mind that, slanted as it may be, all sides in a rhombus are equal in length.
 
        
        
        
Answer:
The other leg is 6 and the Hypotenuse is 6√2
Step-by-step explanation:
because it's a 45 45 90 the legs equal and the Hypotenuse is square root 2 times leg
 
        
             
        
        
        
Note: Consider "÷" sign instead of "=".
Given:

To find:
The quotient.
Solution:
We have,

It can be written as

Splitting the middle terms, we get


Taking out the common factor (x-1), we get

Cancel the common factors.

The quotient is  .
.
Therefore, the correct option is D.
 
        
                    
             
        
        
        
Use pemdas (parenthesis, exponents, multiply/divide, add/subtract);
5.9(4) + 4³ + 3.86
5.9(4) + 64 + 3.86
23.6 + 64 + 3.86
The answer is C) 91.46
