From sin(180-x) = sin(x) 
sin(150) = sin(180-30) = sin(30) 
sin(120) = sin(180-60) = sin(60) 
from cos(360-x) = cos(x) 
cos(300) = cos(360-60) = cos(60) 
cos(210) = cos(360-150) = cos(150) 
from cos(180-x) = -cos(x) 
cos(210) = cos(150) = cos(180-30) = -cos(30)

Answer:
C
Step-by-step explanation:
In order to write the equation, you need to identify the slope and y-intercept. 
1) the y intercept is what y is when x=0. According to the table, it is -2. 
2) the slope is the change in the y values over the change in the x values.  Notice that the y values are increasing by one for every increase in 1 in the x values, so the slope is 1/1 or 1.
3) we can then put those values into slope-intercept form which is y=mx+b where m is the slope and b is the intercept. 
4) so the equation is y=(1)x-2 or y=x-2  (they are the same)

In the US, the gallon is a unit of measurement for liquids like milk, fuel, and water. If the petrol in your automobile is nearly empty, you should stop and get at least a few more gallons. A gallon is equal to 4 quarts, or 3.785 liters, of liquid.
<h3>Explain about the gallons?</h3>
Eight pints make up a gallon, which is a unit of measurement for liquids. It is equivalent to roughly 4.546 liters in Britain. It is roughly equivalent to 3.785 liters in America.
A gallon of water in the US weighs 8.345 pounds or 3.785 kilogram at 17 degrees Celsius, while a gallon of water in the imperial system weighs 10.02 pounds or 4.545 kilogram. The Imperial gallon weighs 16.6% less than 1 US gallon (gal).
Gas consumption is affected by driving on hills and mountainous terrain, by the state of the roads (such as stop-and-go city traffic or highway travel), and by the weather (such as high winds or snow). We can safely infer that under a number of
Answer is 14 gallons of gas need to travel 406 miles
