If 

 is the variable of the horizontal axis, then you can solve for 

 to get the equation of the line in slope-intercept form in the 

 plane:

i.e. a line with slope 

 through the origin, which means it is contained in the first and third quadrants. Since the terminal side of 

 has a negative sine, the angle must lie in the third quadrant.
Because the slope of the line is 

, you can choose any length along the line to make up the hypotenuse of a right triangle with reference angle 

. Any such right triangle will have 

, regardless of whether the angle is the first or third quadrant. But since 

 is known to lie in the third quadrant, and so 

 and 

 are both negative, you have
 
 
        
        
        

,    we know that on Month 0, the Books were 80

we also know that on the first month there were 100 books,

now, how many books when t = 8?   A=80(1+0.25)⁸, or A=80(1.25)⁸.
 
        
                    
             
        
        
        
Answer:
We have 8 liters of 54% alcohol.
We will add "x" liters of 66% alcohol to make "8 +x" liters of 65% alcohol.
54 * 8 + 66 x =   65 (8 + x)
432 + 66x = 520 + 65x
x = 88 liters

Answer:
40 degrees and 45 degrees
Step-by-step explanation:
If you subtract 95 degrees from a 180-degree triangle, you are left with 85 degrees. To proportionally split them, find two values that add to the same value. Since 40 and 45 make up 80 and they multiply by two to make 80:90, these are the two measures.
