Answer:

Step-by-step explanation:
We are given that: 

Where <em>A</em> is in QI. 
And we want to find sec(A). 
Recall that cosecant is the ratio of the hypotenuse to the opposite side. So, find the adjacent side using the Pythagorean Theorem: 

So, with respect to <em>A</em>, our adjacent side is 63, our opposite side is 16, and our hypotenuse is 65. 
Since <em>A</em> is in QI, all of our trigonometric ratios will be positive. 
Secant is the ratio of the hypotenuse to the adjacent. Hence: 

 
        
                    
             
        
        
        
Suppose the smallest angle is x
the largest is 5x-3
the remaining angle is 2x-1
the three angles make a sum of 180: x+5x-3+2x-1=180
8x-4=180
8x=184
x=23
the smallest angle is 23 degree.
        
             
        
        
        
Answer:
10 hrs
Step-by-step explanation:
d = rt, solved for t, is t = d/r.
We need to find t here.
t = d/r = (60 miles) / (6mph) = 10 hrs

Answer:
5
Step-by-step explanation:
2 out of 9 games won
After the N games, the games won would be HALF. Thus, we can write a ratio and solve for the variable N:

Now we cross multiply and solve for N [the number of remaining games that all are won]:

N represents 5
