bear in mind that tangent is sine/cosine or y/x
for the tangent to be negative, the signs of "y" and "x" must differ, and that happens only on the II and IV quadrants
and for the tangent to be positive, the signs must be same, and that's only on I and III quadrants.
where's the graph??
I can't answer this without the graph

C. 10
Step-by-step explanation:
Supplementary means that they form a 90° angle.
Hello!
To first solve this problem, let's look at how much the workers would've finished when they were still a group.
Since the job could've been originally done in 11 days with 7 people, and they only worked for 3 days (with 7 people), they originally finished 3/11 of the job.
Now, let's look at how much each person finishes of the job in one day.
Since 7 workers can finish the job in 11 days, this means that 1 worker can finish the job in 77 days, translating to that one worker does 1/77 of the job in one day.
Let's connect these ideas. There is 8/11 of the project remaining, and this was finished in 14 days. This means, every day, 4/77 of the project was finished. (8/11 divided by 14)
Since we know one worker does 1/77 of the job per day, and every day, 4/77 of the job was finished, 4 workers were on the team.
Therefore, 7-4, 3 workers left the team.
Hope this helped!
