Midpoint formula is
 ---------------(1)
 ---------------(1)
Here

Substituting values in equation (1)


 
        
             
        
        
        
<span>x = angle 90 - x = measure of complement of x 180 - x = measure of supplement of x From the information given in the problem, we get this: 180 - x = 7 (90 - x) 180 - x = 630 - 7x -x + 7x = 630 - 180 6x = 450 x = 450/6 x = 75. Now we prove that x = 75° is the correct angle: x = 75° = measure of angle 90° - 75° = 15° = meaure of complement 180° - 75° = 105° = 7 (15°)</span>
        
                    
             
        
        
        
The y int. is correct but you wrote it wrong it is (0, -2)
        
             
        
        
        
Answer:
h = 8
Let the unknown number be h for height
V = LWH
984 = 20.5 x 6 x h
984 = 20.5 x 6h
984 = 123h
984 ÷ 123h
= 8
 
 
        
             
        
        
        
6.3 because you round 6.324 to get 6.3
