Answer:
C
Step-by-step explanation:
the legs of a 30-60-90 triangle are 1 and  , while the hypotenuse is 2.
, while the hypotenuse is 2.
the ratio of the legs is therefore 1 :  → C
 → C
 
        
             
        
        
        
Adults = 9
Children = 2
Let x be the number of adults.
11-x is the number of children.
22x + 15(11-x) = 228
22x + 165 - 15x = 228
22x - 15x = 228 - 165
7x = 63
7x / 7 = 63 / 7
x = 9  number of adults.
11 - x = 11 - 9 = 2 number of children.
To check:
22x + 15(11-x) = 228
22(9) + 15(11-9) = 228
198 + 30 = 228
228 = 228
(not my answer btw)
