Answer:
y = 120
x = 10.6
Step-by-step explanation:
Given polygons are parallelograms.
In parallelograms, consecutive angles are supplementary which means their sum is equal to 180.
Since two parallelograms are similar:
60 + y = 180 subtract 60 from both sides
y = 120
To find the value of x:
side lengths are proportional because these are similar polygons
 cross multiply fractions
 cross multiply fractions
18x + 72 = 264 subtract 72 from both sides
18x = 192 divide both sides by 18 
x = 10.6 approximately
 
        
             
        
        
        
63/240 seats or 21/80
The greatest common denominator is 3, so you would divide both by 3.
