Answer:
 
Step-by-step explanation:
Tan (300°) can be written as Tan (360°-60°)   ---1
Using identity :

Using 1
So, 
The value 
So, 
Thus the exact value of    
  
 
        
                    
             
        
        
        
Answer:
<h2>Yes, because 5²+12²=13²</h2>
Step-by-step explanation:
Yes
 
        
                    
             
        
        
        
we have
6x+3y=12 -----> line p
Find the slope
3y=-6x+12
y=-2x+4
m=-2
-4x=2y-2 -----> line Q
2y=-4x+2
y=-2x+1
m=-2
therefore
the lines are parallel because their slopes are equal
 
        
             
        
        
        
Answer:
5/6
Step-by-step explanation:
The months of the year are: January	February	March April May June July	August September October	November December	
There are 12 months
There are 10 months that do not start with A
P (month
that does NOT begin with the letter A)
 = number of months that do not start with A / total months
 =10/12
  =5/6
