Figures of same shape and size are similar .Two circles  C1&C2 will be similar.
Circle 1 has a center of (-4,5) and circle 2 has a center of (2,1) .The x of the center is having the translation x+6 and the y  is having a translation of y-4.The center of the circle is dilated by 3 units.
The circles are similar because you can translate Circle 1 using the transformation rule (x+6,y-4 ) and then dilate it using a scale factor of 3.
2) Area of sector =  ÷360.
÷360.
Where α is the angle made at center.
Area of given sector= π(12)(12)(60)÷360 =24π.
 
        
             
        
        
        
The correct answer is 140 because the mean, average, number from July per day represents how many people would have visited each day if they were all even. 
 If there were 20 more people each day in August, the mean would be 140. This would represent how many people visited each day.
        
                    
             
        
        
        
Answer:
C
Step-by-step explanation:
The angle is total is 138 degrees. Part of the entire angle is already given (the 88 degree measure), so all you have to do is subtract 88 from 138, which is 50.
 
        
                    
             
        
        
        
paso a paso
Step-by-step explanation:
tienes que saber cuanto le quito al otro por que 
el primero es 168 y el otro es 138 cubro le quito 30 y el otro 
es 123 igual tienes que quitarle tal ves es sumarle primero y después 2 de restarle 
espero que te sirva
