4/1 / 5/2 = 4/1 * 2/5 = 8/5 
1 7/8 = 15/8
15/8 * 8/5 = 120/40 = 12/4 = 3 inches
 shorter side should be 3 inches
 
        
             
        
        
        
Answer:
1.55 feet. 
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle R = 24°
Hypothenus = RS = 3.8 feet
Opposite = ST = x
The value of x can be obtained by using the sine ratio. This is illustrated below:
Sine R = Opposite / Hypothenus 
Sine 24 = x / 3.8
Cross multiply 
x = 3.8 × Sine 24
x = 3.8 × 0.4067
x = 1.55 feet
Thus, the Lenght ST is 1.55 feet. 
 
        
             
        
        
        
Answer: b. The adjacent angles formed by two intersecting lines are supplementary.
Step-by-step explanation:
In the given picture , we can see that there are intersecting lines with adjacent angles which have shown.
If we add the adjacent angles for each pair of intersecting lines we get,



Therefore,b is the right option "The adjacent angles formed by two intersecting lines are supplementary."
- Two Angles are supplementary when their sum is 180 degrees. 
- Two Angles are complementary when their sum is 90 degrees. 
- Vertical angles are always equal.
 
        
                    
             
        
        
        
32200 divide by the number of days in a year 365
32200 / 365 = 88.21
about 88 per day
