Answer:
   C.  12
Step-by-step explanation:
Corresponding sides are proportional. Sides with the same mark are the same length.
   WX/XY = LM/MN = LM/KJ
   WX/10 = 18/15
   WX = 180/15 . . . . multiply by 10
   WX = 12
 
        
             
        
        
        
Answer:
50 degrees
Step-by-step explanation:
We know that an inscribed angle in a circle is 1/2 the arc that it inscribes. So, therefore the arc is inscribed by the 25 degrees is 50. Assuming that the center of the circle is O, the center angle will be the arc measure. Knowing this, angle a is 50 degrees. If you're curious about all these theorems, they can be proved using similar triangles. 
fyi, using the same logic, angle b is 25 degrees
 
        
             
        
        
        
15 boxes is three times 5 boxes so the number of dishes in 15 boxes is
3 * 125 
 = 375 dishes
 
        
             
        
        
        
1225.
It is also called 35 squared. It is 35X35
The power is how many times you multiply the number by itself.
