Yes, but it could be more thorough, like for example:<span>a small domesticated carnivorous mammal with soft fur, a short snout, and retractile claws. It is widely kept as a pet or for catching mice, and many breeds have been developed.</span>
        
                    
             
        
        
        
Convert miles/hour to meters/second:
42mi/hr(0.447) = 18.77m/sec
        
             
        
        
        
86% bc 50 is easy to work with, you know 43 arent red, and since 43x2=86 its 86, multiply by 2 bc 50 is half of 100
        
             
        
        
        
Answer:
Angle 1 = 41°
Step-by-step explanation:
Since they are both vertical angles
(6x+11)° = (10x-9)°
6x - 10x = -9 - 11
-4x = -20
4x = 20
x= 5.
Therefore, 
Angle 1 = 6(5) + 11
Angle 1 = 30 + 11
Angle 1 = 41°
