Obtuse triangle and x=38
Step-by-step explanation:
38 + 104 + x = 180
142 + x = 180
x = 38
 
        
             
        
        
        
The end result will not be the same as the beginning number because of the change in amounts in-between. Here's an example similar but easier
I have two dollars
I get half of it more 
I now have three dollars

Now I have a dollar and a half
It all depends on that the course if of the numbers
 
        
             
        
        
        
Answer:
Step-by-step explanation:
3x + 4(x - 8) - x = 3/5 (10x + 15)
3x + 4x - 32 - x = 3(2x + 3)
6x - 32 = 6x + 9
This is what I did. I'm not sure that this problem has a solution
 
        
                    
             
        
        
        
3h - 27 = 36
3h = 63
h = 21
