Answer:
m3 should be 70°
all internal angles of a triangle add up to 180
180-35-75 = 70
 
        
                    
             
        
        
        

Domain restrictions are what x values make the denominator zero. 
a² + 5a - 36 = (a + 9)(a - 4) 
a ≠ -9 ; a ≠ 4 
 
        
             
        
        
        
Answer:
A: 105.6 B: 26.40
Step-by-step explanation:
if you divide 132 by 5, you get Meteorite B, 26.40, then minus that from 132, and you get Meteorite A, 105.6. 
To check, do 26.40x5 and you should get 132.
 
        
             
        
        
        
75.
Explanation: from 3 to 12, you add 9, and then double the 12 to get to 24, and then add 9 again to get to 33, and double it to get 66, so the pattern is to add 9 and then double.
