We have similar triangle trianges ABC ~ ADE so
BC:AB = DE:AD
BC:2  = 10 : (2+3) = 10:5 = 2:1
So BC=4 because 4:2 = 2:1
Choice C.
 
        
             
        
        
        
 Answer:
x = 70
y = 110
z = 30
Step-by-step explanation:
all triangles add up to 180
30 + 80 = 110
180 - 110 = 70
x = 70
30 + 40 = 70
70 + 80 = 150
180 - 150 = 30
z = 30
40 + 30 = 70
180 - 70 = 110
y = 110
 
        
             
        
        
        
Answer:
 
  
And rounded up we have that n=421
Step-by-step explanation:
We know that the sample proportion have the following distribution:

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by  and
 and  . And the critical value would be given by:
. And the critical value would be given by:
 
The margin of error for the proportion interval is given by this formula:  
 (a)
    (a)  
And on this case we have that  and we are interested in order to find the value of n, if we solve n from equation (a) we got:
 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  
 (b)
   (b)  
We assume that a prior estimation for p would be  since we don't have any other info provided. And replacing into equation (b) the values from part a we got:
 since we don't have any other info provided. And replacing into equation (b) the values from part a we got:
 
  
And rounded up we have that n=421
