Answer:
3
Step-by-step explanation:
Function B  looks like   y = 3x + 4
with Function A being y = 9x + 4
9 is 3 times more than 3
 
        
             
        
        
        
The answer is B because if 0 is < y than 8 would be equal to x
        
             
        
        
        
To find the measure of the s angle que are going use the cosine law because we know all the sides of the triangule:
s² = r² + t² - 2*r*t * cos(S)
Then solve the equation 
s² -r² - t² = -2*r*t * cos(S)
arccos ((s² -r² - t² /-2*r*t)) = S
arccos (((250)² -(850 cm)²-(940 cm)² /(-2* 850 cm*940 cm) = S
14.9 = S
round to the nearest 10th of a degree 
15º = S
