Clearly

corresponds to a point on the fourth "circle" in the plane.

is a rotation of 120 degrees counter-clockwise relative to the positive side of the horizontal axis, which corresponds to a clockwise turn of 360 - 120 = 240 degrees.
This means (C) is the answer.
The solution for this problem is 9.45
Answer: -1.5
because one of the numbers is - 10 => the other is 15/-10 = -1.5
Step-by-step explanation:
This situation is represented in annex.
From Pythagorean theorem you've got equation:

There isn't any solutions where x>0, so this situation is IMPOSSIBLE.
