Since it is a given that the angles are vertical, then that means they have to be congruent or = to each other so we can now set up an equation:
3x+7=x+53
Now we need to get the variable alone on one side so subtract 7 from the left (remember what you do, you must do to both sides)
3x=46
Now we can divide by three to get x alone
x=15.333333333 or rounded to 15.33
 
        
                    
             
        
        
        
Answer:
x = 115°
Step-by-step explanation:
These angles are actually alternate exterior angles.
Alternate exterior angles are congruent.
 
        
                    
             
        
        
        
Answer:
the volume of the sphere is 507.78981 cm^3
Step-by-step explanation:
The computation of the volume of the sphere is given below:
Given that
The Diameter is 9.9 cm
So, the volume of the sphere is 
= 4 ÷ 3 ×π × r^3
= 4 ÷ 3 × 3.14 × 9.9 ÷ 2^3
= 4 ÷ 3 × 3.14 × 4.95^3
= 507.78981 cm^3
Here r denotes the radius
And, the radius would be comes by dividing the diameter from 2 
Hence, the volume of the sphere is 507.78981 cm^3
 
        
             
        
        
        
Converting 200 miles to the amount of carbon dioxide emission that would be 1.884 tons annually. This will be the amount of carbon dioxide given that 200 miles is monthly covered.
