Answer: 30° and 110°
55° and 85°
70° and 70°
The sum of angles in a triangle is 180°. Therefore, since an angle has been given as 40°, the remaining angles will be:
= 180° - 40°
= 140°
Therefore, 
30° + 110° = 140°
55° + 85° = 140°
70° + 70° = 140°
 
        
             
        
        
        
When two variables are inversely proportional the relation between them can be written as:

Here, k is the constant of proportionality and is always equal to the product of the two variables. So using the given values of z and x, we can find k first.

The constant of proportionality for the given inverse proportion comes out to be 2. Using the value of k in the equation, we get:

We have to find the value of z when x=28. So replacing x by 28, we get:

Thus, rounding of to nearest thousand the value of z comes out to be 0.071 if x is equal to 28.
 
        
             
        
        
        
D should be correct because you add all the boxes that’s inside the rectangle
        
                    
             
        
        
        
Answer:
x=4
Step-by-step explanation:
4(3x+5)=6(x+8)-x
Distribute
12x +20 = 6x +48 -x
Combine like terms
12x+20 = 5x+48
Subtract 5x from each side
12x-5x +20 = 5x-5x+48
7x +20 = 48
Subtract 20 from each side
7x+20-20 = 48-20
7x = 28
Divide each side by 7
7x/7 = 28/7
x = 4
