Step-by-step explanation:
 
        
             
        
        
        
All you need is the double angle identity:

So we have

Apply the identity again to the squared term:

 
        
             
        
        
        
Completing the square is done as follows:
1. Write the equation in a way that the constants are in the right side while the terms with x are on the left. 
<span>9x2 +54x = 7
</span>
2. Make sure that the coefficient of the x^2 term is 1.
<span>9(x2 + 6x) = 7
</span>
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
<span>9(x2 + 6x + 9) = 7 + 81
9(x+3)^2 = 88
</span>
        
                    
             
        
        
        
Answer:
<u>The missing angle measures also 110°</u>
Step-by-step explanation:
Let's recall that If the transversal cuts across parallel lines (apparently, this particular case) then those alternate exterior angles have the same measure (.∠ 110° and ∠?) So in the figure given, the two alternate exterior angles measure the same.
<u>The missing angle measures also 110°</u>
