Answer: A

Step-by-step explanation:  A reference angle is smallest possible angles that  terminal side makes with the x- axis. Since 190 degrees is located i the 3rd quadrant we use the formula 190-180 to find the possible answer and in this case it is A, 10.

I need help with this !! chart
Burka [1]

Answer:

Make coordinates with this table.

Step-by-step explanation:

What I think from these tables is that you can make coordinates with these points. Here are the instructions for you to follow-

  1. See the "y" and "x". These are the axis. So make coordinates with these. Ex- (0,3), (1,5) and so on
  2. Plot these coordinates in a graph paper.
  3. After plotting them, you might find the shape it made.

I hope it helps you.
