Answer:
30 feet
Step-by-step explanation:
Let x be the length of the ladder. Then, x cos(60) = 15
If we divide both sides by cos(60), then x = 30 feet.
 
        
                    
             
        
        
        
Answer:
Shortest Leg: 5 inches, Hypotenuse: 13 inches
Step-by-step explanation:
A right triangle follows the pythagorean theorem, a^2+b^2=c^2. C is the hypotenus. A combination found using this is 5, 12, and 13. To double check this, we know that the hypotenus is 2x+3, where x is the smallest leg. 
 
        
             
        
        
        
Answer:
Interest = $47.34
Step-by-step explanation:
Formula:-
Simple interest I = PNR/100
P - Principle amount  
N - number of years
R - Rate of interest
It is given that
P = $ 1600
R = 6%
Number of days = 180 days
<u>To find the simple interest for 1 year(365 days)
</u>
 I = PNR/100
 = (1600 * 1 * 6)/100 = $96
<u>To find the interest for 180 days
</u>
For 365 day I = $96
For 180 days I = (180/365) * 96
I  = $47.34
