Answer:
B
Step-by-step explanation:
Supplementary angles sum to 180°, hence
3x + 9 + 2x + 2 = 180, that is
5x + 11 = 180 ( subtract 11 from both sides )
5x = 169 ( divide both sides by 5 )
x = 33.8
Hence the smaller angle has a measure of
2x + 2 = (2 × 33.8) + 2 = 67.6 + 2 = 69.6° → B
 
        
             
        
        
        
Answer:
k=67/1360
Step-by-step explanation: Step 1: Simplify both sides of the equation.
201=4080k
Step 2: Flip the equation.
4080k=201
Step 3: Divide both sides by 4080.
4080k
4080
=
201
4080
k=

Answer:
100,000,000 goes 10 times into 1,000,000,000
 
        
                    
             
        
        
        
3.2-5.7=-2.5 so its have to be a negative because a smaller number subtract a bigger number have to be equal to a negative number.
