Answer: I believe it is C.
Step-by-step explanation: Because if you take 4 x 20 = 80
If  I am wrong sorry.
 
        
             
        
        
        
Nice fact I guess 
I don’t know 
        
             
        
        
        
keeping in mind that parallel lines have the same exact slope, hmmmm what's the slope of the line above anyway?

so we're really looking for the equation of a line whose slope is 1/3 and runs through (18,2)

 
        
             
        
        
        
Answer: -1
Step-by-step explanation:
You want to find an angle that is coterminal to 495. So, subtract 360 degrees until youre in the range of 0-360. I got 495 - 360 = 135°
Tangent is equal to  , we already solved theta which was 135°
, we already solved theta which was 135°
This next part is hard to explain to someone who doesnt know their trig circle, idk if you do. The angle 135 is apart of the pi/4 gang. So we know this is going to be some variant of √2/2. Sine of quadrant 1 and 2 is gonna be positive:

Now lets do cosine of 135°, which again is apart of the pi/4 gang because its divisible by 45°. Its in quadrant 2 so the cosine will be negative.

The final step is to divide them. They are both fractions so you should multiply by the reciprocal.
