Answer:
The length of x=3/1
Step-by-step explanation:
Given the right triangle
Ф = 30
We know that
sin Ф = opposite/hypotenuse
The opposite of angle 30° = x
The hypotenuse is = 6
so 
sin 30 = opposite/hypotenuse
     1/2      = x/6           ∵ sin 30 = 1/2
      1/2 × 6 = x
      6/2 = x
        3/1 = x
Therefore, the length of x=3/1
 
        
             
        
        
        
Answer:
15%
Step-by-step explanation:
The cost of 2 adults and 2 children without the discount is
2 adults = 2 (55) = 110
2 children = 2 (45) = 90
Total cost = 110+90 = 200
The original price is 200 and the new price is 170
Percentage discount = (Original price - new price)/ original price * 100%
                                      = (200-170)/200 * 100%
                                      = 30/200 * 100%
                                      = .15 * 100%
                                      = 15%
