Answer:
No, it is not a right triangle.
Step-by-step explanation:
Using the property of the right triangle, square root (5^2 + 10^2) = 5root(5), and it is not equal to 15, so it is not a right triangle.
 
        
                    
             
        
        
        
Your total expense would be 35$ because 25+10=35 and then since you are talking about money you add the money sign. Your answer would be 35$
        
             
        
        
        
This problem basically already gives you X, you just have to simplify.
To complete this problem all you have to do is divide 11 by 9.6
11 / 9.6 = 1.15
So X = 1.15
