Answer:
B
Step-by-step explanation:
Given that r is inversely proportional to s then the equation relating them is
r =  ← k is the constant of proportion
 ← k is the constant of proportion
To find k use the condition r = 16 when s = 3
k = rs = 16 × 3 = 48
r =  ← equation of variation → B
 ← equation of variation → B
 
        
             
        
        
        
Answer:
x=10
Step-by-step explanation:
these are similar triangles
8             12 
------   = -----------
x+4          2x+1
using cross products
8* (2x+1) = 12(x+4)
distribute
16x + 8 = 12x+48
subtract 12x from each side
16x-12x +8 = 12x-12x+48
4x+8 = 48
subtract 8 from each side
4x+8-8 = 48-8
4x = 40
divide by 4
4x/4 = 40/x
x =10
 
        
             
        
        
        
Answer:
20 degrees
Step-by-step explanation:
If BD is the angle bisector of ABC, then ABD must equal half of that. 40/2=20 degrees. Hope this helps!
