I think it might be 43° because since the line is going through the middle, it would be 180-47-90=43 (the 90 came from the right angle)
hope this helps! :)
        
                    
             
        
        
        
Answer:
1/2 <3/4
Step-by-step explanation:
1/2   vs 3/4
We need a common denominator of 4
1/2*2/2   vs   3/4
2/4  vs 3/4
Since the denominators are the same, we compare the numerators
2 <3  so
2/4 < 3/4
1/2 <3/4
 
        
             
        
        
        
There are 7,920 minutes in 5.5 days
60minutes in an hour
24hours in a day
60 times 24 times 5.5 = 7,920

Answer:

Step-by-step explanation:
Supplementary angles are angles equal to 180°. 
Therefore:

Now that we have our equation, let's distribute the  and the
 and the  into the parentheses they are next to:
 into the parentheses they are next to:

Combine like terms:

Subtract  from both sides of the equation:
 from both sides of the equation:

Divide by the coefficient of  , which is
