Starting from the fundamental trigonometric equation, we have
Since 
, we know that the angle lies in the third quadrant, where both sine and cosine are negative. So, in this specific case, we have
Plugging the numbers, we have
Now, just recall that
to deduce
The arithmetic sequence is the first one.
Answer:
A
Step-by-step explanation:
Answer: I cannot see the answer choices, so there is nothing to go by to answer this question.
Step-by-step explanation:
What I can tell you is that a line being parallel to another line would look like this: \\.
Two lines close to each other and that look identical are parallel.
Parallel lines never intersect each other, for that would make them perpendicular to each other.
In equation form, two lines can be found parallel to each other if they have the same slope. Often times they differ in y-intercepts, but they are still parallel.
