Hello!
Let O be the center of the sphere, A the tangency point and B the location of the satellite.
m<ABO = 1/2m(b) = 1/2 * 138 = 69
m<OAB = 90
m<AOB = 180 - 90 - 69 = 21
21 * 2 = 42
The answer is 42°
Hope this helps!
        
             
        
        
        
Answer:
It is not C got it wrong.
Step-by-step explanation:
 
        
                    
             
        
        
        
2y=2_8 
2y=_6
Divide both sides by 2 so that y can stand alone 
Therefore y=_3
        
                    
             
        
        
        
Answer:
-2
Step-by-step explanation:
5n+3= -10
5n = -13
n = -13/5
 = -2.6
question is integer 
so answer is -2
 
        
             
        
        
        
Replace every x you see in the function with 1 and simplify.
Let x be 1.
f(1) = 4(1)^2 -(1) + 3
f(1) = 4(1) - 1 + 3
f(1) = 4 - 1 + 3
f(1) = 3 + 3
f(1) = 6
Done!
