Answer: The number of child tickets is 85 and the number of adult tickets is 95.
Step-by-step explanation:
Let C = Number of child tickets
 A = Number of adult tickets.
As per given, we have
C+A=180          (i)
7C+13A=1830           (ii)
Multiply 7 to both sides of equation (ii), we get
7C+7A=1260     (iii)
Eliminate (iii) from (ii) , we get

Put value of y in (i), we get
C= 85
Hence, the number of child tickets is 85 and the number of adult tickets is 95.
 
        
             
        
        
        
Polygon FGHIJ is the result of the rotation of ABCDE. 
A = F ⇒ 117°
B = G ⇒ 90°
C = H ⇒ 127°
D = I ⇒ 90°
E = J ⇒ 117°
The measure of angle BCD remains the same because the rotation involves the whole polygon. Thus, it is still 127°
