Answer:
   reflection, then rotation, then translation
Step-by-step explanation:
Read the problem statement. It tells you the sequence:
Triangle A B C is <em>reflected</em> across B C to form triangle A prime B C. Triangle A prime B C is <em>then rotated</em> about point A to form A prime B prime C prime. Triangle A prime B prime C prime is <em>then shifted to the right</em> to form A double-prime B double-prime C double-prime. 
The transformations are ...
   reflection, then rotation, then translation
 
        
                    
             
        
        
        
The value of x that makes m║n is 40° 
<h3>Line of transverse on parallel lines:    </h3>
In geometry, the line that intersects two straight lines at distinct points is known as a transversal. 
<h3>Corresponding angles: </h3>
The angles that are formed when two parallel lines are intersected by a third line i.e a transversal are corresponding angles. 
Note: 
Two corresponding angles are formed by a transversal with two parallel lines that are equal 
Here we have 
The angle made by the intersecting line with line m is 120° 
And the angle made by the same line with line n is 3x° 
Let us assume that m║n  
From above observations 
The given angle are corresponding angles 
=> 3x° = 120° 
=> x° = 40°  
Therefore, 
The value of x that makes m║n is 40°

Answer:
x ≈ 8.66
Step-by-step explanation:
Using the sine ratio in the right triangle
sin60° =  =
 = 
Multiply both sides by 10
10 × sin60° = x, thus
x ≈ 8.66 ( to 2 dec. places )

Answer:
C should be next
Step-by-step explanation:
Ok after you add 3x to both side you should get this:
5=5x+9 
It makes since o subtract 9 from both sides at least for me.
Hope this helps :D
