Answer:
40.4
Step-by-step explanation:
Well...you see, 60% of $97 is equal to 58.2. you can get this by multiplying 97 by 0.60.
so subtract 97 by 58.2 and you will get 38.8, now you will add the tax which is and extra add-on to the prices full value
and it's a 4% tax so you will add for percent to 38.8, 
basically multiply 38.8 times 0.04 and you will get 1.6 which you will have to add the your amount to get 40.4.
 
        
             
        
        
        
Answer:
The answer to your proble I'm slow intercept from is y=-2x+8
Step-by-step explanation:
 
        
             
        
        
        
Set them equal to each other and solve 
3x + 39 = 4x +34
-x=-5
X=5 
Plug it in 
3(5) + 39 = 54 
4(5) +34 = 54
For the final angle , 
54 + 54 = 108
180-108 =72
The angle measures are 54,54, and 72
