Answer:
   12
Step-by-step explanation:
It is worthwhile memorizing the ratios of legs in a 30°–60°–90° triangle. Shortest to longest, the ratios are ...
   1 : √3 : 2
Then the sides marked will have the ratio ...
   6 : x = 1 : 2 = 6 : 12
   x = 12
_____
You can also get there using trigonometry.
   cos(60°) = 6/x
   x = 60/cos(60° = 60/0.5
   x = 12
 
        
             
        
        
        
7=3(5+x). 7 represents the pay altogether. 3 represents the total number of people. 5 represents the price of a ticket +x which represents the coupon
        
             
        
        
        
Answer:
72:48
Step-by-step explanation:
as you divide 120 by 5 as 3+2=5 and that equals 24
24x3=72
24x2=48

ANSWER
(2,2)
EXPLANATION
Since f(x) and its inverse function are symmetric about the line y=x, if (a,b) lies on the graph of f, then (b,a) must lie on f inverse.
The point (2,2) lies on f and the same time on f inverse.
The solution is a point that satisfies both equations.
Hence the correct choice is:
(2,2)
