Step-by-step explanation:
Tom paid 16 dollars for 4 lbs
16/4=4 dollars/ lbs
 
        
                    
             
        
        
        
 
 
Using Heron's formula where s = 9 ...... and a = b = c = the side lengths .....we have......
 
A = √[s(s -a)^3] = √[4*3^3] = √[4*27] = √[4*9*3] = √[36*3) = 9√3 sq. in.
 
        
             
        
        
        
Answer:
a is adjacent, b is opposite, c is the hypotenuse
Step-by-step explanation:
A right angled triangle must contain the opposite, the adjacent and the hypotenuse. The opposite is the side that directly faces the angle of interest. The adjacent is the side that is close to the angle of interest.
Given that the angle Y is positioned between X and Z, the point b becomes the opposite of Y. The point a becomes adjacent to angle Y while c remains the hypotenuse of the right angled triangle.
The image below typifies the explanation given above. It shows the relationship between the three sides of the right angled triangle in detail.
 
        
                    
             
        
        
        
From what I can see, it might be wanting you to find the distance of the lines connecting the 2 points. Use then distance formula to do that.
        
             
        
        
        
<em>it increases 3° each hour</em>
3*2= 6
6° after 2 hours
3*3= 9
9° after 3 hours
3*6= 18 
18° after 6 hours
