Given:
tan x = 3/y
cos x = y/z
Because tan x = sin(x)/cos(x), therefore
sin x = tan(x)*cos(x)
         = (3/y)*(y/z)
         = 3/z
Answer: a) sin x = 3/z

Answer:
0.
Step-by-step explanation:
Add 14 on both sides:
-11v+0=v
So we have:
-11v=v
And there is only one number in the universe that can satisfy that and that is 0.
 
        
                    
             
        
        
        
Answer:
None of the above.
Step-by-step explanation:
n(3 + 2n)
Apply distributive property...
3n + 2n²
There are no extra numbers
 
 
        
                    
             
        
        
        
Answer:
 The scale factor for the resultant rectangle is units.
 units.
Step-by-step explanation:
 Given two rectangles with sides 3 units and 7.5 units.
We have to find the scaling factors so that we can obtain bigger rectangle of 7.5 units from smaller rectangle of 3 units.
Scale factor is defined as the ratio  of corresponding side of given figure to the corresponding side of resulting figure.
That is 
Here, 

Hence, the scale factor for the resultant rectangle is units.
 units.
