Answer: So, the length (L) = 7 3/4 ft = 31/4 (as an improper fraction)
  
the width (W)  = (1/3)xL
  
So the width = 1/3 x (31/4) =
31/12 = 2  7/12 feet
Step-by-step explanation:
 
        
                    
             
        
        
        
The answer is : 1:6 repeating
        
             
        
        
        
Using one of the above equations, you can find the value of x. 
tan x = 84/13 => x = tan-¹(84/13)
x = 81.20°

Answer:
   4 : 9
Step-by-step explanation:
The requested ratio is ...
   tile length : board length = (2/3 ft) : (1/2 yd) = (8 in) : (18 in)
   = 8 : 18 = 4 : 9
_____
To make a unitless ratio, both parts must have the same units. Here, we chose to express the lengths in inches. We could have used feet or yards as well. (2/3 ft)×(1 yard)/(3 ft) = 2/9 yd or (1/2 yd)(3 ft/yd) = 3/2 ft. You get the same ratio with any of these:
   (2/9 yd) : (1/2 yd) = (4 yd) : (9 yd) = 4 : 9 . . . . . multiply by 18
   (2/3 ft) : (3/2 ft) = (4 ft) : (9 ft) = 4 : 9 . . . . . multiply by 6
