If you would like to know what is 3 divided by 5 5/8, you can calculate this using the following steps:
5 5/8 = 45/8
3 divided by 5 5/8:
3 / 5 5/8 = 3 / 45/8 = 3 * 8/45 = 8/15
The correct result would be 8/15.
        
                    
             
        
        
        
Answer:
x = 13
Step-by-step explanation:
Note that the side length x is opposite of the right angle, which means that it is the hypotenuse, which will usually be denoted as c.
Set the equation: 
a² + b² = c²
let: 
a = 5
b = 12
c = x
Plug in the corresponding numbers (& x) to the corresponding variables:
(5)² + (12)² = (x)²
Simplify. First, solve for the power, and then add: 
x² = (5²) + (12²)
x² = (5 * 5) + (12 * 12)
x² = 25 + 144
x² =  169
Next, root both sides of the equation: 
√x² = √169
x = √169 = √(13 * 13) = 13
x = 13

Note the rules, and it should be easier: 
30-60-90° = 1 , √3 , 2
45-45-90° = 1 , 1 , √2
Any other measurements use the equation:  a² + b² = c²
 
        
             
        
        
        
Answer:
x=5
Step-by-step explanation:
3x^2=15x
Subtract 15x from both sides
3x^2-15x=0
Factor out 3x
3x(x-5)=0
Since 0 divided by any number is zero, we get that:
x-5=0
x=5

Answer:
   yes
Step-by-step explanation:
The 7 angles listed have a total of 946 degrees. The total interior angle measure in an octagon is 1080 degrees. So, the remaining angle must have a measure of 134°. The figure is entirely feasible.
